Subject: Best way to strsplit a column
Hello,
I have a data.frame with a column that I would like to split into based
around the delimiter ":". This is a useful feature in Excel. I cannot
work out the best way to do it in R. I am sure you need to use
strsplit, but that returns a list. The problem is that some values in
the column do not contain a ":" so should have a "NA" in the second
column of the result, and this makes doing an unlist a non-starter.
Any ideas?
Many thanks
