Dear R-guRus: I have 2 questions 1) I have 2 variables, e.g. x<-5; y<-"Char" How do I create a new variable which would have both these values in a string (e.g. "5Char", or "5 Char", etc ) ?? 2) if i have an array x[1:100], and I do x[x==345.123], how do I get position j in the array of those x[j] which are equal to 345.123 ? Thank you very much, Vlad. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- 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 !)

1) paste(x,y) 2) see the function 'which'. However the exact equality test ('==') is not appropriate here: you need to test for near equality.
