Dorothea,

Im not familiar with this function, but perhaps something like this may
work... You should remove the lines where there are NA.

data2 <- data[-which(is.na(data[1:nrow(data),])),]

or you may want to take a look at complete.cases function

?complete.cases

but both will remove all lines in the data with any NA in it. It means that
if will analyze data from variable 2 and 3 and the line has NA only in
variables 4 and 5 then it will be removed anyway. Thus you may need to edit
a little you removing step.

Kind regards,

Abraço forte e que a força esteja com você,
