Get a subset

[stella]

Hi, I have a list of names (alphanumeric characters) and each row by itself contains a different number of names seperated by a semicolon (";"). There are also rows with no entry. I would like to have the name before the first semicolon in each row, if there is any entry. Does anyone have an idea how to solve this in R? Thank you! Stella

You can use gsub() to delete all the characters after the first
semicolon by replacing them with "". If you provide the requested
reproducible example, I imagine someone will provide you with working
code, if reading the help for gsub() isn't enough to get you going.
