dear all, I got a problem with pattern matching using grep. I extracted a list of characters from a data frame, and I tried to match this list of characters to a column from another data frame. In return, I got only one match, but there should be far more matches. Any ideas what has gone wrong?
Another question, if I also want to match the whole of the elements against the non-initial parts of the elements in another table. Which command should I use?
