Dear R useRs, Sorry for this foolish question, but I can't find how to escape the * character when using grep : > grep("-", c("/3", "2*3", "4-4")) [1] 3 > grep("/", c("/3", "2*3", "4-4")) [1] 1 > grep("*", c("/3", "2*3", "4-4")) Erreur dans grep("*",

Dear useRs, I'm trying to create a barplot like so: x=matrix(1:10,2,5) barplot(x,leg=c("left","right"),besid=T) The legend is placed in default position topright, however the data are plotted there too. I tried controlling the legend position by adding x="topleft" but this results in an error that x matches multiple formal arguments. Leaving out the legend

Hi, ascii is a new R package for writing asciidoc or txt2tags document with embeded R commands. It provides: - a generic method for common R objects: ascii(). Default argument depends of R object. - two Sweave drivers: Sweave("yourfile.Rnw", RweaveAsciidoc) or Sweave("yourfile.Rnw", RweaveT2t). This package is very similar to xtable or R2HTML. It is very interesting if you

Hello, ascii package has been updated to version 0.3.2. ascii is a R package for writing asciidoc, txt2tags, sphinx or org documents with embeded R code. See http://eusebe.github.com/ascii/ for some examples. News since version 0.2 are: - new sphinx driver and output (see http://sphinx.pocoo.org/) - new org driver and output (see http://orgmode.org/) - ascii.simple.list method - ftable

Hi, I have uploaded a new version of the ascii package, it should be availble on CRAN soon. Major new features are: - pandoc support (http://johnmacfarlane.net/pandoc/) - an alternative to the Sweave "way" to create reports: see ?Report. This feature needs a working installation of asciidoc, txt2tags and/or pandoc. It becomes increasingly difficult for me to maintain and test all
