Kerry,
xlist = {{1, 2, 3}, {{4, 5, 6}, 7, 8}, 9};
Map[f, xlist, {-1}]
{{f[1], f[2], f[3]}, {{f[4], f[5], f[6]}, f[7], f[8]}, f[9]}

Hello,
I'm trying to get Mathematica to do the following:
Suppose
x = {{1,2,3},{{4,5,6},7,8},9}
f = some function
How can I get f applied to each element of x but with the list structure
intact? I.e. I want something that generates:
{{f[1],f[2],f[3]},{{f[4],f[5],f[6]},f[7],f[8]},f[9]}
Thank you!
