is it possible to name the first unnamed automated generated column in a data.frame? as you can see with the following code, i replaced the very first automated generated column with my first column.
if not, how can i access the data there? thank you
df<-data.frame(column1=letters[1:5], column2=1:5, column3=LETTERS[1:5]) rownames(df) <- df[,1] df[,1] <- NULL
