I am trying to rename rows in my dataset. I need to change them like this: first row would be named "IL1", second "IL2",..., "ILn", where n is a number of rows in the dataset. I know how to change it by for example rownames(df) <- c("IL1","IL2","IL3","IL4"). But type it word by word is possible only in smaller datasets. I need to change it in dataset where are hundreds of rows. Any ideas? Thank you.

You can use paste0:
rownames(df) <- paste0("IL", 1:nrow(df))
