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.
