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.
