Subject: numeric operations w/ lists
Hello all,
X is a list of 20 lists, and each individual list has 65 elements.
Y is a list of 65 elements.
WANT: subtract Y from each of the 20 lists in X.
Here's what I tried and the error messages:
> X - rep(Y, 20)
Error in X - rep(Y 20) : non-numeric argument to binary operator
I tried several methods w/o success. Any suggestions kindly
appreciated.
Thanks,
Dave
