Launch a GUI for Compiling and Loading C Code

Description

A GUI interface allows users to edit, compile, and embed C functions in the R environment.

Usage

loadC()

Details

The function loadC() launches an interactive GUI that can be used to manage the construction of C functions intended to be called from R. The GUI provides tools to edit, compile, load, and run C functions in the R environment.

The loadC GUI also includes a tool for comparison between the running times and return values of R and C functions. It is assumed that the R and C functions are named prefix.r and prefix.c, respectively, where prefix can be any user-chosen prefix. If an initialization function prefix.init exists, it is called before the start of the comparison.

The GUI controls:

File Prefix	Prefix for .c and .r files.
Lib Prefix	Prefix for shared library object.
Set WD	Set the working directory.
Open Log	Open the log file.
Open.c File	Open the file prefix.c from the working directory.
Open .r File	Open the file prefix.r from the working directory.
COMPILE	Compile prefix.c into a shared library object.
LOAD	Load the shared library object.
SOURCE R	Source the file prefix.r.
UNLOAD	Unload the shared library object.
Options
Editor	Text editor to use.
Update	Commit option changes.
Browse	Browse for a text editor.
Clean Options
Select All	Select all check boxes specifying file types.
Select None	Select none of the check boxes.
Clean Proj	Clean the project of selected file types.
Clean All	Clean the directory of selected file types.
Comparison
Times to Run	Number of times to run the R and C functions.
RUN	Run the comparison between R and C functions.
R Time	Computing time to run the R function multiple times.
C Time	Computing time to run the C function multiple times.
Ratio	Ratio of R/C run times.
