integers, but I am not
I have a data frame with integers mixed with a lot of NULLs, how do I convert
that to multiple lists of integers with zero (to replace NULL)? I tried the
following, and they failed:
> dim(g2)
[1] 25352 173
> class(g2)
[1] "data.frame"
> class(g2[1,])
[1] "data.frame"
> g2[1,30:40]
30
