Hello! # I have a data frame x: x <- data.frame(a = 1:10, b = 2:11, c = 3:12, other = rnorm(10)) # First, I need to change every value 7 in columns a:c to 4 # Then, I need to decrease by 1 all values in columns a:c that are >7 What would be the fastest way of doing it? Thank you! -- Dimitri Liakhovitski
