1L, 2L etc are integers. (That is, identical to as.integer(1) ,
as.integer(2) etc)

Using integers (instead of "numeric" type) is more efficient as here
they're used as indexes and would be converted to integer anyway.

1L:p is the sequence 1, 2, 3, ..., p (just like 1:p)

Just for curiosity, what is findFn('cov2cor') ?
