Hi,
I have simple R question.
I have a vector x that contains real numbers. I would like to create another vector col that is the same length of x such that:
if x[i] < 250 then col[i] = "red" else if x[i] < 500 then col[i] = "blue" else if x[i] < 750 then col[i] = "green" else col[i] = "black" for all i
I am convinced that there is probably a very efficient way to do this in R but I am not able to figure it out. Any help would be greatly appreciated.
Thanks in advance, Arend van der Veen
