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
