Dear R-users, It is my understanding that cat(shQuote(a.string)) should print the origintal a.string. Is this right? I am not sure cat() correctly prints strings which are generated by triple-shQuote(): > shQuote(shQuote("a")) [1] "\"\\\"a\\\"\"" > cat(shQuote(shQuote(shQuote("a"))), '\n...

R Community, I often am in need of viewing the reference manuals of packages and do not have Internet access. I have used the code: path <- find.package('tm') system(paste(shQuote(file.path(R.home("bin"), "R")),"CMD", "Rd2pdf",shQuote(path))) someone kindly provided from this help list to generate the manuals from the latex files. This worked well with version R 2.13. After the upgrade to R 2.14 I use this code (see below and get...

Hello, I wanted to ask help about importing sas datasets. 1)I tried with some functions as read.ssd (foreign package), but it doesn't import the file if the length of the variables' names are longer than 8 bite (it has to conform to the 6 version). 2)I then tried with the sas.get function (Hmisc package) but with the command: c<- sas.get(lib="c:\\ghan",

Current R release (3.5.2) and devel return a 0 exit status on error, while prior versions returned a non-zero exit status. On Linux and MacOs, the following line returns TRUE for R-3.5.2 and R-devel, and FALSE for R-3.5.1 and R-3.5.0: system2("Rscript", c("-e", shQuote("stop('foo')"))) == 0 I didn't find this in the NEWS, so I believe this is a bug. Best, Michel

Hi again! While investigating the bug report [*] I found out that on unix, system2 does not quote its `stdin` argument while preparing the command line to launch. It does shQuote the `stdout` and `stderr` arguments, and also the `f <- tmpfile()` variable (which is used if `input` argument is provided), which seems to set a precedent. On Windows, stdin, stdout, and stderr are handled independently of the shell, so it also just works without the use of shQuote by the call...

I noticed a shQuote fix for Windows in the svn logs. Just wanted to point out that this will favorably affect texi2dvi on Windows which previously used UNIX quoting and so generated an incorrect Windows command. (Note that texi2dvi is used when creating vignettes.) Another problem is that the recommended tex distr...

Thomas, As F Harrel in a preceding message told me that you are the maintainer of Hmisc package, I write directly to you, with copy to the Rhelp list in case someone encountered the same problem and find some benefit in the response. I used quite often the function sas.get in Hmisc library which I is very, very useful. But, as trying to reuse it today it seems not to function anymore. I tried

Consider the question we had recently: "how do I count the lines in a file without reading it into R?" The solution I suggested was as.numeric(system(paste("wc -l <", filename), TRUE)) Unfortunately, it doesn't work, or at least, not all the time. If you already know all about that, and don't care, or already have a solution, stop reading now. Otherwise, let

I have 3 SAS files all in the directory F:/sas, two data files and a format file : form.ea1.sas7bdat form.ea2.sas7bdat sas.fmts.sas7bdat F is a USB. I am trying import them to R using "sas.get". I have not used SAS since I was downloading data from mainframe and having to write JCL. I had forgotten how bizarre SAS can be. I currently have not even figured out how to load the files

I am trying to pass a additional argument to texi2dvi, for example to use the aux-directory.
