Hi all, I'm seeing an error on Windows when I try to install a package to a package library path that starts with a digit. I can reproduce the error as follows using R-devel from Feb 24 on Windows advanced server: badLib = "c:\\badExample\\2\\foo" dir.create(badLib, recursive=TRUE) z = .libPaths() z = .libPaths(c(badLib, z)) z [1] "c:\\badExample\\2\\foo"

Hi all, I swear this used to work: library(gsubfn) strapply("S(AC,P)TVDK(8)EELVQK(8), ".[(].{1,2}[)]|.")[[1]] But somewhere along the update path it stopped ... now giving me this Error in base::gsub(pattern, rs, x, ...) : invalid backreference 2 in regular expression Can't figure it out. What am I doing wrong? Thanks for any hints, Joh

Hi, I am looking for a way to extract an "interesting" part of the match to a regular expression. For example the pattern "[./](*.)" matches a substring that begins with either "." or "/" followed by anything. I am interested in this "anything" w/o the "." or "/" prefix. If say I match the pattern against "abc/foo" I

I'm having a Thursday morning mental block, any suggestions on the following would be most appreciated... I have (as an example) surgery = c("d48", "d67", "dnc37", "a75", "d10", "a78", "d31", "d55", "d1") before each number part the possibilities are c("a", "d",

I have a matching problem that I cant solve. mystring = "xxx{XX}yy{YYY}zzz{Z}" where "x","X","y","Y","z","Z" basiclly can be anything, letters, digits etc. I'm only interested in the content within each "{}". I am close but not really there yet. library(gsubfn) strapply(mystring,"\\{[^\\}]+",, perl=F)

Hi, I'm running out of the *numbered* backreferences \\1, \\2, ..., \\9 for gsub(). Does R support *named* backreferences, and if so, what is the syntax? Thanks Henrik

I appears that backreferences when using regexes in node names doesn''t work. Can anyone confirm this? If I''m incorrect, how do I go about using a backreference to the name regex within the node definition container?

Good afternoon list, I have the following character strings; one with spaces between the maths operators and variable names, and one without said spaces. form<-c('~ Sentence + LEGAL + Intro + Intro / Intro1 + Intro * LEGAL + benefit + benefit / benefit1 + product + action * mean + CTA + help + mean * product')

Hello, I am not very familiar with regular expressions and escaping. I need to replace the %-signs in a character vector with elements as "income 0%-33%# to be replaced by "income 0\%-33\%" (for later use in LaTeX). Using gsub("%","\\%","income 0%-33%") does not give the desired result. However, gsub("%","\\\\%","income

Is there a way to rename a function when importing it? I want to say, "import yourFunc from Foo as myFunc" in the NAMESPACE file. Does this exist and I've missed it? If it doesn't exist, would others think it useful (and possible)? Best, + seth

Hi all, One of the things I find most problematic in R is the partial matching of names in lists. Robert and I have discussed this and we believe that having a mechanism that does not do partial matching would be of significant benefit to R programmers. To that end, I have written a patch that modifies the behavior of "[[" as follows: 1. [[ gains an 'exact' argument with

I'm looking for ideas for creating high-quality plots for use in projected presentations (powerpoint, etc) --- ideally high-quality png, jpg, bmp. The graphics produced using the postscript device look very good. Those generated with win.graph(), png are plagued by the jaggy lines. So far, the only way I can use the postscript plots in my presentations is using separate screen capture

Hi, I have a S3 package with namespace called "myS3Pkg". Inside my package I would like to create a S4 class which extends (adds 2 slots) another S4 class from some other package. The class should be created in "myPkg" environment (and not global environment). Using: setClass("myS4class", representation("otherS4class", mydata = "numeric"),

Hi R users, I am a newbie and therefore the naive question. Sorry but I was unable to find an answer online. I would like to read 47 data sets (country1.raw, country2.raw, ... country47.raw) and save into a matrix each time (data1, data2, ....data47). for (i in 1:47){ data(?) <- read.csv(file.path("country", i, ".raw", fsep = ""), header = TRUE) } The read.cvs

Hi all, The dict package provides a dictionary (hashtable) data structure much like R's built-in environment objects, but with the following differences: - The Dict class can be subclassed. - Four different hashing functions are implemented and the user can specify which to use when creating an instance. I'm sending this here as opposed to R-packages because this package will

RDieHarder fails its regression tests on x86_64 (aka "amd64") at CRAN (using Debian), and I see the same on Ubuntu 8.10 in 64 bit. No issues on 32bit. One odd thing is that the program behaves well if run via R --no-save < tests/RDieHarder.R but NOT when started using R --slave < tests/RDieHarder.R as R CMD check does. So I tried different things related to startup
