The easiest is probably read.table(....as.is=c(1,3)....) but you could also do cC <- rep(NA,5) cC[c(1,3)] <- "character" read.table(....colClasses=cC...) which would be more readily generalized to "stranger" data types. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
