[R] print and lapply....

```I meant something like:

TP <- 1:4
lapply(TP, function(x) {
print(x)
print(x^2)
})

You may wish to add cat("\n") after print(x^2) so that your results
from each iteration are separated.
You may also wish to add invisible() around lapply() if you're not
saving / / using the return list in any way.
