Dear kayj,
Try this:
X<-c("ASK", "DGH", "ASG", "AUJ",
"FRT")
res<-data.frame(do.call(rbind,strsplit(X,"")))
colnames(res)<-paste("X",1:ncol(res),sep="")
res
HTH,
Jorge

[R] How to split a character vector into 3 vectors
Another option is:
read.table(textConnection(gsub("(\\w)", "\\1;", X)), sep =
";")

[R] How to split a character vector into 3 vectors
This splits them into a 3 column matrix:> x <- c("ASK", "DGH", "ASG", "AUJ", "URT") > library(gsubfn)> z <- strapply(x, ".", simplify = rbind) > z[,1] [,2] [,3] [1,] "A" "S" "K" [2,] "D" "G" "H" [3,] "A" "S" "G" [4,] "A" "U" "J" [5,] "U" "R" "T" z[,1], z[,2] and z[,3] are your vectors.

someone has probably answered this already but use substr() new variable<-substr(old.variable,1,1) Simon. ----- Original Message ----- From: "kayj" <kjaja27 at yahoo.com> To: <r-help at r-project.org> Sent: Tuesday, February 10, 2009 6:50 PM Subject: [R] How to split a character vector into 3 vectors> > Hi , > > > Does any one know how to split a character vector , I have a vector X that > looks like this and each row has 3 characters > > X > ASK > DGH > ASG > AUJ > FRT > > I would like to split the vector into 3 vectors that look like this > > X1 X2 X3 > A S K > D G H > A S G > A U J > U R T > > thanks > > -- > View this message in context: > http://www.nabble.com/How-to-split-a-character-vector-into-3-vectors-tp21939492p21939492.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >
