Build from source

See https://github.com/rstudio/rstudio/blob/master/INSTALL for installation instruction.

To build Rstudio from source in Ubuntu:

  • Install R.
  • Install Qt 4.
  • Download a release version tarball of source code. Do not grab from github master branch. Sometimes the preview version works but the release version cannot be compiled. For example, the release version 0.98.507 would give a build error from /opt/QRstudio-QtSDK/Desktop/4.8.0/gcc/include/QtCore/gstring.h, but the preview version 0.98.836 (May 11th, 2014) works fine.
  • Make sure git is installed/available.
  • Install dependencies (note that installing boost will take a few minutes. Make sure there are 2GB memory or will get a memory related error when running make install)
cd rstudio-rstudio-dbf531d  # the number at the end depending on the source
cd dependencies/linux
./install-dependencies-debian
  • Create build directory
mkdir build
cd build
  • Configure by running cmake
cmake .. -DRSTUDIO_TARGET=Desktop -DCMAKE_BUILD_TYPE=Release

If something is wrong related to boost library, go back to step 1. Then type (installing boost library takes a while) 

cd dependencies/linux 
run ./install-boost

And for some reason, when I try to run cmake (OS is 32-bit LXLE running on VM), I get the following error 

CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message):
  Could NOT find Qt4 (missing: QT_QTWEBKIT_INCLUDE_DIR QT_QTWEBKIT_LIBRARY
  QT_QTDBUS_INCLUDE DIR QT_QTDBUS_LIBRARY) (found suitable version "4.8.6", minimum required
  is "4.8.0")
  • Build and Install
sudo make install

For RStudio Desktop on Linux, make install automatically creates an entry in the Applications -> Programming menu for RStudio. The rstudio can be launched by /usr/local/lib/rstudio/bin/rstudio.

Preferences

RStudio Theme

Background color (v1.1.383, see an animation on this post)

There are 3 choices of RStudio theme:

  • Classic + selected Editor theme: Code and Console/Terminal are dark, Environment/history/connections and Files/Plots/Packages/Help/Viewer are white (good when doing finding)
  • Modern: 4 panels are all dark
  • Sky: 4 panels are all dark

One good-looking option is also change the layout like this one. So source code take half and console and plot each takes a quarter of the screen.

Toolbar

View -> Hide Toolbar

Change repository

  • chooseCRANmirror(): this actually changes the CRAN mirror
  • setRepositories(ind=1:2): this allows to install packages from Bioconductor. After the change, we can use RStudio or the command install.packages() to install R package from Bioconductor.

In my case, stringr package source code in cloud.r-project.org (default in RStudio or 0-Cloud from chooseCRANmirror()) is 1 week old. That version of source code is now archived and the URL shown from the output of install.packages() cannot be found. When I switch to USA-IA mirror, it has the latest version.

Use options("repos") to see its effect.

Get help on firefox/chrome browser

(The help panel is kind of small)

No, it can't. But alternatively, if we click "Show in a new window" icon, it will bring the help on an independent window. 

> getOption("browser")
function (url) 
{
    .Call("rs_browseURL", url)
}
<environment: 0x1121bda60>

Pop out the source pane

Drag the tab outside the RStudio window to where you want your new code window to appear, or Click the "Show in new window" button on the editor toolbar (it's next to forward/back)

Install on Crouton

Test on my Asus Chromebox/Crouton with Ubuntu 14.04. 

(trusty)brb@localhost:~$ sudo dpkg -i '/tmp/mozilla_brb0/rstudio-1.0.44-amd64.deb' 
Selecting previously unselected package rstudio.

After I run sudo apt-get install libjpeg62, RStudio can be installed successfully.

Switch R version for RStudio desktop

https://support.rstudio.com/hc/en-us/articles/200486138-Changing-R-versions-for-RStudio-desktop

In Linux desktop, we need to run the following (or include the line in ~/.profile file for a permanent solution) before calling 'rstudio' in a terminal. 

export RSTUDIO_WHICH_R=/opt/R/3.5.0/bin/R

Keyboard shortcut

  • https://support.rstudio.com/hc/en-us/articles/200711853-Keyboard-Shortcuts (Help -> Keyboard Shortcut Quick Reference)
  • Customize the shortcuts.
  • https://www.dropbox.com/s/0moch6xocili6v9/RStudio%20Shortcuts.pdf?dl=0
  • Knit an rmarkdown file
    • Mac: Shift + Cmd + k
    • Linux: Shift + Ctrl + k
  • (Aug 16, 2018) for some reason, run current line (CMD+Enter) will send random lines. It does not help if I assign a different key-bind. Update RStudio does not help either.
    • One way it still works is by selecting line(s) first and hitting the key-bind.
    • Another way is to go to Tools > Global options > Code. Change to Current line from the dropdown list next to CMD + Enter executes. The default is "Multiple-line R statements" which should be better since an R statement can spread several lines. The 3rd option "Multiple consecutive R lines" will send a block of R lines automatically which does not look ideal in most cases.

Move focus to source/console

  • Ctrl + 1: source
  • Ctrl + 2: console

These are the default.

Show previous/next Plot

By default, they are "Ctrl + Alt + F11" and "Ctrl + Alt + F12". But they have a conflict with other shortcuts in RStudio IDE itself or with the (Linux/Mint) system. In my case, Ctrl+Alt+F11 will escape from Linux Desktop:( Also the Quick Reference shows these bindings had a conflict: Ctrl + Alt + F11 represents Previous Terminal or Previous Plot.

I change the shortcuts to Alt+Left and Alt+Right (directly use keyboard to change it). It works but there is a delay if the plot is more complicated (6 seconds on a 10000 genes heatmap). These new assignment works on Mac and Linux.

History panel

If we want to rerun lines from the history panel, just highlight the lines and then either click the "To Console" button or press the "Enter" key.

Running A Data Project In R

https://kkulma.github.io/2018-03-18-Prime-Hints-for-Running-a-data-project-in-R/

  • Use R projects. Always
  • Describe the purpose of your code / project.
  • Load all necessary packages in the beginning of your script & consider calling functions in a package via ::
  • Name your code sections and use them for quick navigation
  • Make your life easier and mark your code when you need to
  • Write your code as if someone was going to use it without communicating with you. From. Day. One
  • Name your files like a Pro: Machine readable, human readable & play well with ordering
    • Put something numeric in your file name first.
    • use the YYYY-MM-DD format for dates
    • regular expression and globbing friendly
    • easy to compute on using delimiters
    • left pad other numbers with zeroes
  • With big, complex data projects use project pipeline
    • load.R
    • clean.R
    • func.R
    • do.R
  • Never save your workspace
  • Before publishing/sharing your code, run it in the fresh workspace

Navigation

You create a new code section by writing #### or ---- at the end of any comment that is to become a new code section.
