Hello sir:
There are 2 questions about string.
1 How to calculate the width of a string? e.g string "abc"'s width is 3; 2 How can I get the "substring" in such kind of condition:   "f:\\JPCS_signal.txt" "f:\\PC1_signal.txt" "f:\\PC2_signal.txt"  What I wanna get is "JPCS" "PC1" "PC2".How can I achieve them by R cammand?

Thanks a lot!

My best
