What were you trying to do with names and what has it got to do with missing values?? How are the missing values coded in the csv file? If they are empty fields, read.csv (btw, isn't it easier to export as delimited file and use read.delim?) should handle them automatically, if not, try using the na.strings argument. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
