[R] FW: can't get package boot to load

[Adam D. I. Kramer]

If you check ?library, you will see that the package argument only takes one
packages. So your code was like saying library(package=RODBC, help=boot)
which does not make sense...but which would indeed load RODBC and not boot.
That is why your problem occurred and why your solution worked.
