Hi,
I am sorry, will try to be more exact from now on...
I have a data.frame with a field called Opis. IT contains
sentenses that
I would like to split in words or fields in data.frame...when I say
columns I mean as in Excel table. I would like to split "Opis" into
ten
fields from the first ten words in Opis field.
Here is an example of my data.frame.
'data.frame': 22928 obs. of 12 variables:
$ VrtinaID : int 1 1 1 1 2 2 2 2 2 2 ...
$ ZapStev : int 1 2 3 4 1 2 3 4 5 6 ...
$ GlobinaOd : num 0 0.8 9.2 10.1 0 0.9 2.6 4.9 6.8 7.3 ...
$ GlobinaDo : num 0.8 9.2 10.1 11 0.9 2.6 4.9 6.8 7.3 8.2 ...
$ Opis : Factor w/ 12754 levels "","(MIVKA) DROBEN MELJAST

$ GeolNastOpis : Factor w/ 113 levels "","B. M. S.",..: 56 53 53

$ NacinVrtanjaOpis: Factor w/ 43 levels "","H. N.","IZKOP",..: 26 1

Hope that explains better...
Thank you, m

Hi all,
I have a columnn with text that has quite a few words in it. I would

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.)
words <-"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?"
strsplit(words, " ")[[1]][1:10]
[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)
t(sapply(strsplit(worddf$words, " "), "[", 1:10) )
[,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"
