logical vector as a matrix

I have a vector like this:
h <- c(4, 6, NA, 12) 
and I create the secound logical vector like this:
g <- c(TRUE, TRUE, FALSE, TRUE) 

And my problem is that I would like to get  a new "m" vector as a rasult
"h" and "g"( as dot-matrix printer) but with missed "NA" value, for
example:

m = (4,6,12)
Do you have any idea?
