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

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. |
