Dear Any, Is there a fonction in R to change a string to uppercase ? Thanks for all your help
The following function will do it. But be warned it will only work if all
the input strings are lower case.
Make.To.Upper.Case<-function(my.string){
paste(LETTERS[match(strsplit(my.string,"")[[1]],letters)],collapse="")
}
Make.To.Upper.Case("jhjhaskjdakdsj")
> [1] "JHJHASKJDAKDSJ"

?toupper p.s: By default, generally everything on this list *is* regarding R; hence it would be nice to see a more imaginative subject line. -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of pbrouilly at gphy.campus.univ-poitiers.fr Sent: Wednesday, September 22, 2004 5:43 PM To: r-help at stat.math.ethz.ch Subject: [R] Dear Any, Is there a fonction in R to change a string to uppercase ?
