It's going to depend on how the data missing-ness is represented in the table.
If you have a csv like 1,2,3 1,,3 4,5,6 You automatically get an NA after using read.csv() -- this can be omitted with the na.omit() command if desired. If missingness is somehow encoded other than an empty spot, it may be a bit harder.
