1. Advanced Data Analytics:
R-Studio vs. Rcmdr

2. R-Studio Overview
• R-Studio is an integrated development environment to support the
development of R code
• R-Studio runs in two ways:
– Desktop versions for Linux, Mac, and Windows: Single user, perfect for a
laptop or desktop machine
– Server version for Linux: Allows any number of remote users to run R-
Studio within a web-browser; facilitates sharing of code and data among
team members
• R-Studio uses the graphical environment of the computer to facilitate
interactions with R:
– Console window for typing code
– Data window for reviewing data frame and other data structures
– Workspace for viewing all of the data loaded into R
– Plot area for showing visualizations
– Tabbed window controls to show other displays

6. Rmcdr Overview
• Rcmdr – “R Commander” – is a graphical user interface for statistical
analysis laid on top of R; R runs in another window and can be used
directly at any time; uses buttons and menus extensively and supports
picking variable names from lists
• Rcmdr was purpose built to simplify access to the most essential
statistical analysis methods; more convenient for users who have used
SPSS, SAS or Stata
• Does not provide direct access to the R command line, but does show
the code that is running
• Not richly graphical, but does show three panes:
– Script Window: Shows the most recently run commands/code
– Output Window: Displays statistical output and results from commands
– Messages Window: Shows errors, warnings, and notes

9. Comparison and Guidelines
• R-Studio is more flexible and powerful, and provides direct access to R
code
• Rcmdr is simpler and more user friendly, particularly when focusing on
statistical diagnostics and analysis
• Both are good for viewing data, neither is good for editing it
• Use Rcmdr with structured, conventional data (rectangular, with
variables in columns and cases in rows), whenever the task involves
running statistical tests
• Use R-studio for any project that requires direct interaction with code
and/or manipulation of complex data
• Note that you can invoke Rcmdr from within R-Studio and it will work
fine on a single user installation; also note that when the user requests a
plot in Rcmdr, it will NOT immediately appear in the plot window of R-
Studio – this is a known bug that may be fixed in future versions

10. What Else is Brewing?
• JGR (Jaguar) – A cross platform console interface that
provides a spreadsheet-like data editor
• Deducer – A conventional statistics GUI
overlaid on JGR
• RKWard – A conventional
statistics GUI using KDE
(mainly for Linux, but has a
Windows installer)

11. Demonstrating Mastery
• If you have not already done so, install and run R-Studio
• Import a data set into R-Studio using the “Import Dataset”
dialog (usually a button on the Workspace tab in the upper
right pane)
• In addition, install the Rcmdr package and “library(Rcmdr)”
to start the graphical interface (for assistance, see Chapter 2
of Thomas Hogan’s “Bare Bones R”
• In Rcmdr, make your imported data the “active” data set and
use the menus to run any statistical diagnostic or test
