Hello, i'm a newbie of the really fantastic "R" , but have some problems to define Missing Values from Spss-Files which i import with the read.spss(data) command ! What should i do to recode i.e. the values 9,99 & 999 to NA. Something like this x <- c(9,99,999,NA) x==NA ...do not what i want, because the data.frame show the values 9,99 & 999 and not NA in this fields ? P.S. Perhaps is it easier to define all Missing Values in SPSS to SYSMIS so that i have got a blank and R automatically define's NA to the blanks ??? Best thanks for advance and regards, christian _______________________________________________________________________ 1.000.000 DM gewinnen - kostenlos tippen - http://millionenklick.web.de IhrName at web.de, 8MB Speicher, Verschluesselung - http://freemail.web.de -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
