Hi
Do you have a source data available. Maybe you could try to read it in
such manner that you will get desired result without further adjustment.
See all options in read.* functions.
If you really wanted to split already imported data you will need to use
regular expressions and I am not an expert in them so I cannot help you
much. Maybe you can paste all items in one row together and then strsplit
the vector and bind all rows together.
e.g.
strsplit(paste("a b 10", "c d 15000", sep=" "), " +")
Regards
