Extracting a specific pattern of characters using regular expression

Question

I have the following pattern for a string: "IGHV1-20*00(1374.6),IGHV1-37*00(1333.7),IGHV1-9*00(752.5)". My expected output should look like: "IGHV1-20,IGHV1-37, IGHV1-9".

I'd appreciate any advice on what regex pattern could be defined to extract this output using gsub/str_extract.

Answer 1

I think you want to match anything that:

1, starts with IGHV 2, then a digit followed by '-' 3, one or more digits till the nearest '*'

Try writing a regex with this.
