Install Rtools for Windows users

Install R using binary package

Redhat el6

It should be pretty easy to install via the EPEL: http://fedoraproject.org/wiki/EPEL

Just follow the instructions to enable the EPEL and then from the CLI as root:

yum install R

or via sudo:

sudo yum install R

Install R from source (ix86, x86_64 and arm platforms, Linux system)

Debian system (with arm architecture)

Simplest configuration

On my debian system in Pogoplug (armv5), I can compile R. See R's admin manual. If I don't need x11, I just need to install 2 required packages.

install gfortran: apt-get install gfortran
install readline library: apt-get install libreadline5-dev

Note: if I need x11, I should install

libx11 and libx11-devel, libXt, libXt-devel (for fedora)
xorg-dev (for debian)

I also run apt-get install readline-common. I don't know if this is necessary. Since I don't need x11, I use the option in configure command. After running

./configure --with-x=no --enable-R-shlib

I got

However, make gave errors for recommanded packages like KernSmooth, MASS, boot, class, cluster, codetools, foreign, lattice, mgcv, nlme, nnet, rpart, spatial, and survival. The error stems from gcc: SHLIB_LIBADD: No such file or directory. Note that I can get this error message even I try install.packages("MASS", type="source").

Install r-base and r-base-dev

In fact, if we want to take a short cut, it seems OK to run the following statement to install r-base and all required components for building r-base and extra packages. Notice that for readline package, it installs 'libreadline6-dev' instead of 'libreadline5-dev' as I just did.

Note that I did not touch /etc/apt/sources.list file so I don't know what version of R will be installed by this method.

Web server

shiny

The following is what we see on a browser after we run an example from shiny package. See http://rstudio.github.com/shiny/tutorial/#hello-shiny. Note that the R session needs to be on; i.e. R command prompt will not be returned unless we press Ctrl+C or ESC.

shiny depends on websockets, caTools, bitops, digest packages.

Q & A:

Q: If we run runExample('01_hello') in Rserve from an R client, we can continue our work in R client without losing the functionality of the GUI from shiny. Question: how do we kill the job?
If I run the example "01_hello", the browser only shows the control but not graph on Firefox? A: Use Chrome or Opera as the default browser.
If I run the example "01_hello" on RHEL the first time, it works fine. But if I click 'Ctrl + C' to stop it and run it again, I got a message

Warning in .SOCK_SERVE(port) : R-Websockets(tcpserv): bind() failed. 
Error in createContext(port, webpage, is.binary = is.binary) : 
  Unable to bind socket on port 8100; is it realsy in use?

A: https://groups.google.com/forum/?fromgroups#!topic/shiny-discuss/jZ8S6dHFB6c

Q: Deployment on web. A: Not ready yet. Shiny server platform is still under beta testing. Shiny apps are hosted using the R websockets package which acts more like a tcp server than a web server, and that architecture just doesn't fit with rApache, or even apache for that matter.

RApache

gWidgetsWWW

Rook

Since R 2.13, the internal web server was exposed.

Tutorual from useR2012 and Jeffrey Horner

Here is another one from http://www.rinfinance.com.

Rook is also supported by [rApache too. See http://rapache.net/manual.html.

Google group. https://groups.google.com/forum/?fromgroups#!forum/rrook

Advantage

the web applications are created on desktop, whether it is Windows, Mac or Linux.
No Apache is needed.
create multiple applications at the same time. This complements the limit of rApache.

4 lines of code example.

library(Rook)
s <- Rhttpd$new()
s$start(quiet=TRUE)
s$print()
s$browse(1)  # OR s$browse("RookTest")

Notice that after s$browse() command, the cursor will return to R because the command just a shortcut to open the web page http://127.0.0.1:10215/custom/RookTest.

We can add Rook application to the server; see ?Rhttpd.

s$add(
    app=system.file('exampleApps/helloworld.R',package='Rook'),name='hello'
)
s$add(
    app=system.file('exampleApps/helloworldref.R',package='Rook'),name='helloref'
)
s$add(
    app=system.file('exampleApps/summary.R',package='Rook'),name='summary'
)

s$print()

#Server started on 127.0.0.1:10221
#[1] RookTest http://127.0.0.1:10221/custom/RookTest
#[2] helloref http://127.0.0.1:10221/custom/helloref
#[3] summary  http://127.0.0.1:10221/custom/summary
#[4] hello    http://127.0.0.1:10221/custom/hello

#  Stops the server but doesn't uninstall the app
## Not run: 
s$stop()

## End(Not run)
s$remove(all=TRUE)
rm(s)

For example, the interface and the source code of summary app are given below

app <- function(env) {
    req <- Rook::Request$new(env)
    res <- Rook::Response$new()
    res$write('Choose a CSV file:\n')
    res$write('<form method="POST" enctype="multipart/form-data">\n')
    res$write('<input type="file" name="data">\n')
    res$write('<input type="submit" name="Upload">\n</form>\n<br>')

    if (!is.null(req$POST())){
	data <- req$POST()[['data']]
	res$write("<h3>Summary of Data</h3>");
	res$write("<pre>")
	res$write(paste(capture.output(summary(read.csv(data$tempfile,stringsAsFactors=FALSE)),file=NULL),collapse='\n'))
	res$write("</pre>")
	res$write("<h3>First few lines (head())</h3>");
	res$write("<pre>")
	res$write(paste(capture.output(head(read.csv(data$tempfile,stringsAsFactors=FALSE)),file=NULL),collapse='\n'))
	res$write("</pre>") 
    }
    res$finish()
}

CGHWithR (removed from CRAN)

But it is still working with old version of R.

Creating local repository for CRAN and Bioconductor

How to set up a package repository

Guide: http://cran.r-project.org/doc/manuals/R-admin.html#Setting-up-a-package-repository

NOTE

If the binary package was built on R 2.15.1, then it cannot be installed on R 2.15.2. But vice is OK.

To create CRAN repository

Before creating a local repository please give a dry run first. You don't want to be surprised how long will it take to mirror a directory.

Dry run (-n option). Pipe out the process to a text file for an examination.

rsync -avn cran.r-project.org::CRAN > crandryrun.txt

To mirror only partial repository, it is necessary to create directories before running rsync command.

mkdir /media/WD640/CRAN
mkdir /media/WD640/CRAN/bin
mkdir /media/WD640/CRAN/bin/windows
mkdir /media/WD640/CRAN/bin/windows/contrib
mkdir /media/WD640/CRAN/bin/windows/contrib/2.15
rsync -rtlzv --delete cran.r-project.org::CRAN/bin/windows/contrib/2.15/ /media/WD640/CRAN/bin/windows/contrib/2.15
(one line with space before /media)
rsync -rtlzv --delete cran.r-project.org::CRAN/src/ /media/WD640/CRAN/src/

And optionally

library(tools)
write_PACKAGES("/var/www/CRAN/bin/windows/contrib/2.15", type="win.binary")

We can use du -h to check the folder size.

To create Bioconductor repository

Dry run

rsync -avn bioconductor.org::2.11 > biocdryrun.txt

Then creates directories before running rsync.

The software part (aka bioc directory) installation:

mkdir ~/Bioc/packages/2.11/bioc
mkdir ~/Bioc/packages/2.11/bioc/bin
mkdir ~/Bioc/packages/2.11/bioc/bin/windows
mkdir ~/Bioc/packages/2.11/bioc/src
rsync -zrtlv  --delete bioconductor.org::2.11/bioc/bin/windows/ ~/Bioc/packages/2.11/bioc/bin/windows
rsync -zrtlv  --delete bioconductor.org::2.11/bioc/src/ ~/Bioc/packages/2.11/bioc/src

and annotation (aka data directory) part:

mkdir ~/Bioc/packages/2.11/data
mkdir ~/Bioc/packages/2.11/data/annotation
mkdir ~/Bioc/packages/2.11/data/annotation/bin
mkdir ~/Bioc/packages/2.11/data/annotation/bin/windows
mkdir ~/Bioc/packages/2.11/data/annotation/src
rsync -zrtlv --delete bioconductor.org::2.11/data/annotation/bin/windows/ ~/Bioc/packages/2.11/data/annotation/bin/windows
rsync -zrtlv --delete bioconductor.org::2.11/data/annotation/src/ ~/Bioc/packages/2.11/data/annotation/src

To test local repository

To test CRAN

r <- getOption("repos"); r["CRAN"] <- "http://arraytools.no-ip.org/CRAN"
options(repos=r)
install.packages("pamr")

We can test if the backup server is working or not by installing a package which was removed from the CRAN. For example, 'ForImp' was removed from CRAN in 11/8/2012, but I still a local copy built on R 2.15.2 (run rsync on 11/6/2012).

r <- getOption("repos"); r["CRAN"] <- "http://cran.r-project.org"
r <- c(r, BRB='http://arraytools.no-ip.org/CRAN')
#                        CRAN                            CRANextra                                  BRB 
# "http://cran.r-project.org" "http://www.stats.ox.ac.uk/pub/RWin"   "http://arraytools.no-ip.org/CRAN"
options(repos=r)
install.packages('ForImp')

Note by default, CRAN mirror is selected interactively.

> getOption("repos")
                                CRAN                            CRANextra 
                            "@CRAN@" "http://www.stats.ox.ac.uk/pub/RWin"

To test Bioconductor

options("BioC_mirror" = "http://arraytools.no-ip.org/Bioc")
source("http://bioconductor.org/biocLite.R")
# This source biocLite.R line can be placed either before or after the previous 2 lines
biocLite("aCGH")

If there is a connection problem, check folder attributes.

chmod -R 755 ~/CRAN/bin

Note that if a binary package was created for R 2.15.1, then it can be installed under R 2.15.1 but not R 2.15.2. The R console will show package xxx is not available (for R version 2.15.2).

For binary installs, the function also checks for the availability of a source package on the same repository, and reports if the source package has a later version, or is available but no binary version is.

So for example, if the mirror does not have contents under src directory, we need to run the following line in order to successfully run install.packages() function.

options(install.packages.check.source = "no")

If we only mirror the essential directories, we can run biocLite() successfully. However, the R console will give some warning

Launch Rstudio

If multiple versions of R was detected, Rstudio can not be launched successfully. A java-like clock will be spinning without a stop. The trick is to click Ctrl key and click the Rstudio at the same time. After done that, it will show up a selection of R to choose from.
