Hi all,Thanks for all the help. I managed to do it with what Gaj suggested (Excel :().The last solution from David is also freat i just don't undestand why R put the words in 14 columns and thre rows?
Because the maximum number of words was 14 and the fill argument was TRUE. There were three rows because there were three items in the supplied character vector.
I would like it to put just the first 10 words in source field to 10 diefferent destiantion fields, but the same row. And so on...is that possible?
I don't know what a destination field might be. Those are not R data types.
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 )

Long ago, before embarking on what eventually ended mainly in statistics, I did two years of geology, so (and also because of knowing what the poster's institute does) I even kinda imagine what these data are.
