Dear List, I'm getting the error: object of type 'closure' is not subsettable And am not sure how to get around the problem. I've included two short code sets below. One that shows what I want to do and works, but without using the function much, and another that tries to use the function but causes the error.
# THIS WORKS AND SHOWS WHAT I'D LIKE TO DO a <- c(1,2,3) b <- c(5,6,0) c <- data.frame(a,b) # TAKES THE MAX OF TWO VARS AND SAVES IT TO A NEW VARIABLE AND DELETES OLD VARIABLES consolidate.fun <- function( data, var1, var2, saved.max ) { max <- apply( data[,c(var1, var2)], 1, max) # THIS WORKS BUT I HAVE TO CALL THE DATA FRAME BY NAME RATHER THEN USING THE FUNCTION DATA NAME c[,"var.max"] <<- max c$a <<- NULL c$b <<- NULL } consolidate.fun( data=c , var1="a", var2="b", saved.max="var.max" ) c # THIS SHOWS THE MORE COMPLETE USE OF THE FUNCTION'S INTENT, BUT # CAUSES THE ERROR IN R. a <- c(1,2,3) b <- c(5,6,0) c <- data.frame(a,b) # TAKES THE MAX OF TWO VARS AND SAVES IT TO A NEW VARIABLE AND DELETES OLD VARIABLES consolidate.fun <- function( data, var1, var2, saved.max ) { max <- apply( data[,c(var1, var2)], 1, max) # SOURCE OF ERROR. I'VE TRIED CALLING THE DATA FRAME IN DIFFERENT # WAYS, BUT NONE SEEM TO WORK FOR ME. data[, saved.max ] <<- max data[, var1 ] <<- NULL data[, var2 ] <<- NULL } consolidate.fun( data=c , var1="a", var2="b", saved.max="var.max" ) c Any helpful comments would be appreciated. mailto:dyo...@telefonica.net ______________________________________________ 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.
