similar to: defining a print method

Can someone verify whether or not this is a bug. When I substitute all occurrence of "\\B" with "X" R seems to correctly place an X at all non-word boundaries (whether or not I specify perl) but "\\b" does not seem to act on all complement positions: > gsub("\\b", "X", "abc def") # nothing done [1] "abc def" >

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

That's an interesting example, as it's conceptually similar to what Pavel is proposing, but structurally different. gsubfn() is more complicated than a simple switch in the body of the function, and wouldn't work well as an anonymous function. Multiple dispatch can nicely encompass both of these cases. For replace(), library(S7) replace <- new_generic("replace",

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

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')

This could be extended to sub and gsub as well which gsubfn in the gusbfn package already does: library(gsubfn) gsubfn("^..", toupper, c("abc", "xyz")) ## [1] "ABc" "XYz" On Fri, Mar 3, 2023 at 7:22?PM Pavel Krivitsky <p.krivitsky at unsw.edu.au> wrote: > > Dear All, > > Currently, list= in base::replace(x, list, value)

There was a discussion on r-help of getting the output from print.packageInfo into a file. Spencer and I have added a file= argument to print.packageInfo for consideration in R. Had this been available it would have simplified the answer to that thread. If the file= argument is used then the packageInfo information is sent to the file specified rather than displayed using file.show .

Dear all, let's assume I have a vector of character strings: x <- c("abcdef", "defabc", "qwerty") What I would like to find is the following: all elements where the word 'abc' does not appear (i.e. 3 in this case of 'x'). Since I am not really experienced with regular expressions, I started slowly and thought I find all word were

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

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

Dear R users, Inspired by previous list discussion of the glob2rxc function, I am attempting to create a new vector called TOTAL by summing all vectors whose names begin with ABC: TOTAL = sum(list = ls(pattern = glob2rx("ABC*"))) I'm running R 2.2.1 on Windows XP. Can anyone say what I'm missing? Thank you, Mark

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 >

Hi all. I am wrting a small content management tool for my company and was trying to display some images from our file store shown below. <td> <img src="\\xx.xx.xxx.xx\xx\xx\xxx\abc.gif"/> The app was displaying the image when it is under the \public\images directory. Is there anything special we need to do to get a file from outside the root of the application? Any help

Hi, I have two asterisk servers with the same version of 1.4.29.1. The first server named it as MYE1. MYE1 is an incoming server that can accept incoming calls from PSTN(ZAP E1). The second server is a pbx functions server and named it as MYPBX(SIP). The sip.conf of MYE1 likes below: [MYPBX] type=peer host=mypbx.abc.com nat=no disallow=all allow=g729 canreinvite=yes qualify=no context=default

Hello all, I’m trying to add some data points to a wireframe. X an Y axis are independent variables, Z axis is predicted probability. I’d like to add the original data points on which the predicted probabilities are based to the wireframe. I’ve followed some of the previous post on this but get stuck : ## first part yields the wireframe## setwd("C:/Temp") rnp <-

If changes to sprintf behavior are being considered, would it be possible to allow some of the other K&R conversion specifiers? xX - for integer to hex conversion, and c - for ascii value to character conversion would all be useful for me.

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.

Why doesn't R have one, like "." in Perl or juxtaposition in awk? It does not seem impossible to introduce one, if that would be reasonable. It would seem to involve adding a table entry to main/names.c for the binary operator and a corresponding internal function, say do_dot(). This cannot be simply do_paste(), since the implied separator is "". So, do_dot() might be
