hello r users, i'm trying to use the apply method on a function with several inputs, but cannot figure out how to send multiple arguments to the function (not multiple runs of the same function, but one run of the function including two variables - each used within the function).
a <- c(1:10,999,999,999) b <- c(11:20,999,999,999) tfun <- function(x,y){ if( (x = 1 & y !=999) || (x > 1 & x < 999 & y == 999) ) x1 <- 1 else x1 <-0 } #this doesn't work - gives an error " 'y' is missing tfilt <- sapply(data.frame(a,b), tfun) thanks, joe -- View this message in context: http://r.789695.n4.nabble.com/using-the-apply-method-for-functions-with-multiple-inputs-tp3054719p3054719.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
