Answer 1

To change the column names of a data frame, you can do this:

# Example data frame
x <- as.data.frame(
    matrix(letters[1:10], nrow = 2)
    );

# Change names of columns 2-5
colnames(x)[2:5] <- paste0(colnames(x)[2:5], 1:4);
# Change all column names
colnames(x) <- paste0(colnames(x), 1:5);
