Print 20 first elements of 2 columns ingnoring NA's

I have data frame with 5 columns.
I want to print the first 20 rows of columns 1 and 2 ignoring all the rows with NA's.

I don't want to change the data frame and remove all NA's
any ideas?


How about this:

myData = data.frame(x = sample(c(NA, 1:5), 50, replace = T), 
                    y = sample(c(NA, 1:5), 50, replace = T), 
                    z = sample(c(NA, 1:5), 50, replace = T))

#Ignore row when NA in column 1 or 2
#Ignore row when NA in any column
