Squaring one column of data
Hi,
A fairly basic problem I think, here although searching the inetrnet doesn't
seem to reveal a solution. I have a dataset with two columns of real
numbers. It is read in via read.table. I simply need to square the data in
the second column and then plot it. I have tried extracting the second
column (b <- z[2]) and then squaring it and merging it to a variable which
is the first column
