[Rd] win.version() incorrect
On Windows 8.1 I get this. win.version() indicates build 9200 but I
actually have build 9600 as can be seen from the ver command.
shell("winver") also indicates 9600. I assume ver and winver are
correct and win.version() is not.
> win.version()
[1] "Windows 8 x64 (build 9200)"
> shell("ver")
Microsoft Windows [Version 6.3.9600]
> R.version.string
[1] "R version 3.0.2 Patched (2013-11-25 r64299)"

[Rd] file.exists does not like path names ending in /
If a path name ends in slash then file.exists says it does not exist.
I would have expected these to all return TRUE.
> file.exists("/Program Files")
[1] TRUE
> file.exists("/Program Files/")
[1] FALSE
> file.exists(normalizePath("/Program Files/"))
[1] FALSE
> R.version.string
[1] "R version 3.0.2 Patched (2013-11-25 r64299)"
I am using Windows 8.1 .

[Rd] How to debug an R package (with C code)
Hi all, Sorry to bother you. I am a beginner in R programming. I have encountered some problems when I modified a R package with C code. I would like to modified the C code within the R package, and want to debug the C program. But I have no idea how to debug this kind of R package. In the package, a R file named aaa.R use the interface .call(bbb.c, ...) to call the C code named bbb.c. And what I did is that I resourced aaa.R and ran it in R Stdio again, after modifying bbb.c. But there is nothing happened. I am very sure that the all the path of R file and C file is correct. And I am using Windows operating system. Could anyone give me a few pointers on how to debug R packages (or extensions with C++/C code)? If possible, Could you please give me an simple example or some command lines?
