[R] file.link fails on NTFS
Windows 7 64-bit, R 2.15.2 i386. Working directory is on an NTFS drive. writeLines(, file.txt) file.link(file.txt, link.txt) Warning in file.link(file.txt, link.txt) : cannot link 'link.txt' to 'link.txt', reason 'The system cannot find the file specified' No link is created. The 'link.txt' to 'link.txt' is suspicious. Does this happen to anybody else? I didn't find anything in my searches.

[R] system(wait = FALSE) seems to fail
I'm having problems with system(wait = FALSE) with R 2.12.1 (both i386 and x64 versions) on a 64-bit Windows 7 machine. This is as expected: print(system(cmd /c dir, wait = TRUE)) This fails: print(system(cmd /c dir, wait = FALSE)) I did not see this with 2.12.0, and things seem to work fine with R 2.12.1 on a 32-bit XP machine. Can anybody else confirm what I'm seeing here?

[R] R 2.11, shell, spaces
Can somebody confirm some unexpected behavior? This is under Windows, with R 2.11.0 and 2.11.1. 1. Create a trivial test file (I called it test.R) containing: cat(Success.\n) 2. Load R (Gui or Term) and run: shell(\C:\\path\\to\\Rscript.exe\ \C:\\path\\to\\test.R\) In my case, I get various error messages. If the path\\to\\Rscript.exe has spaces or not, it complains that the first token (e.g., 'C:\Program') is not a valid command. If the path\\to\\Rscript.exe has no spaces, it complains that the specified path is invalid. If C:\\path\\to\\test.R has no spaces, and I remove the surrounding quotes, things work as expected. I think this might be related to some earlier e-mail traffic that I didn't see a satisfactory resolution to.

Re: [R] R 2.11, shell, spaces
Thanks, Duncan, for the pointer in the right direction. I didn't realize cmd's treatment of quotes was so odd. For the curious, the quote behavior of cmd (under XP) is here, in the Remarks under Processing quotation marks: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/cmd.mspx?mfr=true In my case I can use system. The only workaround I could think of for executing a command that requires a shell (e.g., using redirection) is to create a temporary batch file and cmd that, which is a bit ugly. Again, thanks for all the input.

R is trying to execute cmd /c c:\path\to\Rscript.exe c:\path\to\test.R and that doesn't work. You'll have to ask Microsoft why, but I believe the correct syntax is cmd /c c:\path\to\Rscript.exe c:\path\to\test.R i.e. /c is followed by just one quoted string, not two. If you need extra quotes because of spaces in the path to Rscript, I don't know what you can do. I'd recommend using system() instead of shell(); it will call Rscript directly, not go through the cmd shell.

[R] 2.7.0 graphics changes and png devices
Hi, I have a question about the graphics changes in 2.7.0. The example is this bit of code: par(mfcol = c(2, 3)) for(i in 1:6) plot(1:10, 1:10, xlab = xlab, ylab = ylab, main = main) In 2.7.0, if I do this interactively (using windows()), I get bold titles. If I do this through a png device, I get regular weight titles. If I do this in 2.6.2, both situations give bold titles. I assume the 2.7.0 png device is off here, but I'm not sure how to fix this. Suggestions?

Re: [R] 2.7.0 graphics changes and png devices
Apologies for the double-post, but I figured I should be slightly more specific. I'm using the windows version of 2.7.0 and 2.6.2. My calls to png is simply png(2.7.0.png) and png(2.6.2.png), respectively, followed by the appropriate dev.off().

[R] cor -1
I'm having what looks like a quantization problem with cor on R 2.7.0. I get warnings from cor.test because r -1. R session output is at the bottom. A simple fix would be to add the appropriate checks to the end of the internal cor code.

[R] pairs, par(plt)
I'm having some confusion over the coordinate system after using pairs. I'm not interested in the content of the actual pairs plot, although the number of pairs seems to matter a bit. I'm purely interested in knowing where my points will be plotted on the device. However, after using pairs, the par information (omd, fig, plt, and usr) don't reflect what points does. For example: pairs(iris[1:5]) par(xpd = NA) points(0 - 0.01 * 1:100, 0 - 0.01 * 1:100) points(0 - 0.01 * 1:100, 1 + 0.01 * 1:100) points(1 + 0.01 * 1:100, 0 - 0.01 * 1:100) points(1 + 0.01 * 1:100, 1 + 0.01 * 1:100) par(c(omd, fig, plt, usr)) The resulting plot shows that the corners of the are approximately 0.05 user coordinate units from the boundaries of the plot region. According to par, though, there is a margin around the plotting region that is clearly not symmetric and does not correspond to around 0.05 units. If we use pairs(iris[1:2]) and repeat the rest, the corners are now 0.02 user coordinate units. par provides the same information as before. So: 1. How do I figure out where coordinates I give to points will display on the figure? 2. More generally (for my own understanding), why does the par information not do what I expect? Do I have some fundamental misunderstanding of the arrangement of plotting, figure, display, and margin regions within the device? I'm using R 2.5.1, and this behavior occurs on a fresh R console.
