R Pros and Con

Free open source and widely used.

Can be integrated with other languages (C/C++, Java).

R can interact with many data sources and other statistical packages (SAS, Stata, SPSS, and Minitab).

For the high performance computing task multiple cores, either on a single machine or across a network.

R: A Command line

interface (CLI)

Users type commands to perform a statistical analysis.

Is preferred for advanced users allows direct control, more accurate, flexible and the analysis is reproducible.

Graphical User Interface

(GUI)

A tool to provide an event-driven user interface.

An extra layer between the user and the program

Based on menus, dialog boxes, icons and controls.

Window, icon, menu, and pointing device (WIMP) paradigm

R GUI Projects

Integrated development environment (IDE)/Script Editors aimed to provide feature-rich environments to edit R scripts and code: Rstudio (www.rstudio.com), and architect (www.Openanalytics.eu)

Web based application: the Rweb (Banfield, 1999), R.Net (www.u.arizona.edu/~ryckman/Net.php), or gWidgetsWWW (Verzani, 2012).

R GUI Projects

Python: OpenMeta-Analyst (Wallace et al, 2012) Java: JGR (Java GUI for R), Deducer (Fellows,

2012), and Glotaran (Snellenburg, 2012). Php: R-php (http://dssm.unipa.it/R-php/) Shiny C++, C# Other extensions connect R to graphical

toolboxes for developing menus and dialog boxes: Tcltk, Gtk.

We focus on Tcltk and Shiny

R GUI Tcl/Tk

Most commonly used: easy, no additional software needed and ready to be used in R (tcltk package)

R-Tcl/Tk interface from the tcltk package (Dalgaard, 2001 and Welch, 2000).

The tcltk package allows the use of the Tk(toolkit) graphical user interface elements within R by embedding Tk commands into the R language.

R GUI Tcl/Tk

R GUIs developed by using tcl/tk or RGtk:• LimmaGUI (Wettenhall and Smyth, 2004),

• LMMNorm (Haldermans, 2010),

• IsoGeneGUI (Pramana et al. , 2010, 2012)

• NeaGUI (Pramana et.al, 2013)

• Rcommander (Fox, 2005)

• RcmdrPlugin.biclustGUI (Pramana, 2011)

RGUI, How to Build One?

Choose one of RGUI categories, and tools to be used (tcltk, java, etc.) which suit with the package purpose.

Make sketches of the window box and consider:

• Input

• Options

• Output

Can all functions be run in a single window (e.g. neaGUI)? Or a main window with menu (IsoGeneGUI) and separate dialog boxes are needed?

25R

GU

I

Create Main Window

tt <- tktoplevel()

tkwm.title(tt,"My New GUI")

topMenu <- tkmenu(tt)

tkconfigure (tt,menu=topMenu)

fileMenu <- tkmenu(topMenu,tearoff=FALSE)

openMenu <- tkmenu(topMenu,tearoff=FALSE)

tkadd(openMenu,"command",label="xls file",

command= getXls)

tkadd(openMenu,"command",label="text file”)

26R

GU

Create Main Window

tt <- tktoplevel()







command= getXls)

tkadd(openMenu,"command",label="text file”)

getXls <- function () {

fileName <- tclvalue(tkgetOpenFile(filetypes=

gettext(' {"Excel Files" {".xls"}} {"All Files"

{"*"}}')))

data <- get( fileName) }

tkadd(fileMenu,"command",label="Quit",command=function() tkdestroy(tt))

tkadd(topMenu,"cascade",label="File",menu=fileMenu)

Summary

A GUI could help novice R users for utilizing all the power of R.

Increase the use of our package/methods especially by scientists with no/less knowledge of R.

A GUI could help novice R users for utilizing all the power of R.

Increase the use of our package/methods especially by scientists with no/less knowledge of R.

Things to consider in developing a GUI:

• Type of GUI (spreadsheets, menu/dialog boxes),

• Tool to develop (tcltk, java)

• Embedded/Independent.

• Single/Multi dialog boxes
