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')

Dear friends of R, I want to produce a pdf file with the contents of a matrix. I employ the latex command in combination with dvi, both contained in the Hmisc package. It seems to me that the function does not correctly set the directory. > tbl.loc <- matrix(1:4, nc=2) > latex.obj <- latex(tbl.loc) > dvi(latex.obj) warning: extra args ignored after 'cd' H:\PROJECTS\data

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

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.

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

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 distribution for Windows, fptex, does not have texi2dvi in the first place. The

Hi, I don't know if I am the first one to report the problem: in 2.8.0 dev2bitmap gained aa support, but "extra" is null if neither taa nor naa is specified. > dev2bitmap("plot.pdf",type="pdfwrite") Error in paste(shQuote(gsexe), " -dNOPAUSE -dBATCH -q -sDEVICE=", type, : object "extra" not found >

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

Is it just me, or did a corrupt PACKAGES.gz file get installed in the bin/windows/contrib/3.2 directory of CRAN mirrors recently? gzfile() complains about it and Cygwin's gzip cannot decompress it. I tried the following repos <- "https://cran.rstudio.com" v <- "3.2" pkgs.gz <- paste(sep="/", repos, "bin/windows/contrib", v,

In the following session we define an xx class and a print method for it. If I invoke it with print then it prints as expected but if we just type xx at the R prompt then we get nothing back. How do we define the print method so that it works in the latter case too? > xx <- structure("abc", class = "xx") > print.xx <- function(x, ...) shQuote(x) > print(xx) #

Hi, I'm currently in the process of writing an R-installation SOP for my company. As part of that process I'm using the recommendations from the 'R Installation and Administration' document, section 3.2, "Testing an installation". This is done on an XP machine, using the latest binary of 2.11.0. The binary is downloaded and then installed from the installer. I then

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

Hi, I am trying to run the command: R CMD INSTALL -l mypath mypackagename from within R (Windows XP) using system() and get the following error: ARGUMENT 'CMD INSTALL -l D:/R/JMB.LIBS jmb.test' __ignored__ Fatal error: you must specify '--save', '--no-save' or '--vanilla' My function contains these 3 lines: setwd("D:/R/R.pkgs") # path to files set

Hi Dan, sorry for the precedent email, I created a csv file of only 1000 records by mistake, that's why R has only read 1000 records. regards Anna ----- Messaggio Inoltrato ----- Da : "a.martino at crismaitalia.it" <a.martino at crismaitalia.it> A : "Daniel Nordlund" <res90sx5 at verizon.net>,<r-help at stat.math.ethz.ch> Oggetto : RE: [R] importing

I am trying to pass a additional argument to texi2dvi, for example to use the aux-directory. Looks like this is not possible via options: options(texi2dvi='texi2dvi --tex-option="-aux-directory=auxdir"') texi2dvi(file = "GBPL3.tex", pdf = TRUE) #Error in system(paste(shQuote(texi2dvi), "--version"), intern = TRUE) : # '"texi2dvi
