Thnaks a lot for your help Sabine There are multiple approaches, but you need to be careful, since it appears that your object is a factor. Thus you may need to convert to a character vector first: title_cat - factor(Training) substr(as.character(title_cat), 1, 1) [1] T Otherwise: title_cat - Training substr(title_cat, 1, 1) [1] T See ?substr for more information.
