[R] string split at xth position

[arun]

Hi,

You could use:
library(stringr)
?str_sub()
lapply(2:3,function(i) if(i==2) str_sub(x,end=i) else str_sub(x,i))
#[[1]]
#[1] "a1" "a2" "a1"

#[[2]]
#[1] "b1" "b2" "b2"
A.K.

Subject: [R] string split at xth position

Hi,

I have a vector of strings like:
c("a1b1","a2b2","a1b2") which I want to spilt into two parts like:
c("a1","a2","a2") and c("b1","b2,"b2"). So there is
always a first part with a+number and a second part with b+number.
Unfortunately there is no separator I could use to directly split
the vectors.. Any idea how to handle such cases?

/Johannes
