[R] How to separate the string?

[Petr PIKAL]

Hi

If you have data frame like this

test=data.frame(x=c("abcd", "abc", "abcde"))
than
strsplit(as.matrix(test), "")

makes a list with splitted character vectors. If you want them in data 
frame you would need to combine vectors of unequal length.

However I would try reading your text file with

read.fwf(file, 1)

Regards
Petr
