David, It seems that your solution works, but why would that be? And why would this NA behavior be platform or version specific? I really need to check with a newer version of R...

I don't think it is platform or version specific. The purpose of the missing value, NA (i.e. Not Available), is to flag the value for special handling in some way, often by deletion. You cannot assume that NA will be treated as any other value since that would defeat the whole purpose of flagging the value as missing. Similar results occur if you try to create tables or cross-tabulations of variables that include NAs with table() and xtabs().

Hi David But the final problem was that Ivan's code with original data (with NA) provided different result on his Mac with R3.2.1 version and on my PC with R3.3.0 devel version.
