Yes -- it's written as a static analyzer so it doesn't execute the
function in question; hence it won't experience the side effects of
package loading.
For example:
f <- function(x){print("Hello World!"); x + 3}
checkUsage(f) # Doesn't print anything
Similarly, library() in f won't have any effect until f is executed.
