Hi, Ok, i got this now. At least i think so. I got a data.frame with 15 fields, all other words have bee truncated. Which is what i want. But ia have that in a seperate data.frame from that one it was before (would be nice if it would be in the same ...)
'data.frame': 22801 obs. of 15 variables: $ V1 : chr "HUMUS" "SLABO" "MALO" "SLABO" ... $ V2 : chr "IN" "GRANULIRAN" "PREPEREL" "VEZAN" ... $ V3 : chr "HUMUSNA" "PEŠČEN" "MELJAST" ",KONGLOMERAT," ... $ V4 : chr "GLINA" "PROD" "PROD" "P0ROZEN," ... $ V5 : chr "Z" "DO" "DO" "S" ... $ V6 : chr "MALO" "r" "r" "PLASTMI" ... $ V7 : chr "PODA," "=" "=" "GFs," ... $ V8 : chr "LAHKO" "8Q" "60mm," "SIVORJAV" ... $ V9 : chr "GNETNA," "mm," "S" "" ... $ V10: chr "RJAVA" "S" "PRODNIKI," "" ... $ V11: chr "" "PRODNIKI" "MALO" "" ... $ V12: chr "" "DO" "PEŠČEN" "" ... $ V13: chr "" "R" "S" "" ... $ V14: chr "" "=" "TANKIMI" "" ... Now, i have another problem. Is it possible to count which word occours most often each field (V1, V2, V3, ...) and which one is the second and so on. Ideally to create a table for each field (V1, V2, V3, ...) with the word and thenumber of occuraces in that field (column) . I suppose it could be done in SQL, but what since i saw what R can do i guess this can be done here to?

Because the maximum number of words was 14 and the fill argument was TRUE.

This would trim the extra columns (in this example set to those greater than 8) by adding a lot of "NULL"'s to the end of a colClasses specification .... at the expense of a warning message which can be ignored: > read.table(textConnection(words), fill=T, colClasses = c(rep("character", > 8), rep("NULL", 30) ) , stringsAsFactors=FALSE ) V1 V2 V3 V4 V5 V6 V7 V8 1 I have a columnn with text that has 2 I would like to split these words in 3 but just first ten words in the string.
