in R, I type in this command x<-c(TRUE,FALSE,NA) then it returns the correct response "TRUE,FALSE,NA"
When i use it in both VB6.0 and C#, the function Evaluate() will return an array of object, and the values in it is "false","false","error 2042(in vb) / -2146826246(in c#) ", the first value is wrong. But if i Evaluate("x<c(TRUE,FALSE)") without "NA", the return values is right? how can i deal with this condition? _______________________________________________ Rcom-l mailing list Rcom-l@mailman.csd.univie.ac.at http://mailman.csd.univie.ac.at/mailman/listinfo/rcom-l More information (including a Wiki) at http://rcom.univie.ac.at
