Hi all,
I have a columnn with text that has quite a few words in it. I would
like to split these words in separate columns, but just first ten
words in the string. Is that possible in R?
Not sure what a column means to you. It's not a precisely defined R
type or class. (And you are requested to offered a concrete example
rather than making us guess.)

[1] "I" "have" "a" "columnn" "with" "text"
"that" "has" "quite" "a"
Or if in a dataframe:
> words <-c("I have a columnn with text that has quite a few words in
it.", "I would like to split these words in separate columns", "but
just first ten words in the string. Is that possible in R?")
> worddf <- data.frame(words=words)

[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,
8] [,9] [,10]
[1,] "I" "have" "a" "columnn" "with" "text" "that" "has"
"quite" "a"
[2,] "I" "would" "like" "to" "split" "these" "words" "in"
"separate" "columns"
[3,] "but" "just" "first" "ten" "words" "in" "the" "string."
"Is" "that"
