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

If I understand you correctly, you have this vector:
x <- c("ASK", "DGH", "ASG", "AUJ", "URT")
This code seems to do what you want:
x1 <- substr(x, 1, 1)
x2 <- substr(x, 2, 2)
x3 <- substr(x, 3, 3)
There's probably a much simpler and more elegant way to do it, though.

# dummy example data
n = 3
x = replicate(10, paste(sample(letters, n), collapse=""))
y = lapply(1:n, function(i) substr(x, i, i))
# if you need a specific vector
x1 = y[[1]]
# if you really need all three as separate variables
for (i in 1:n)
assign(paste('x', i, sep=""), y[[i]])
vQ
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
