simple<-function() {
if(exists("height"))
cat("height exists\n")
else
cat("height does not exist\n")
}
foo<-function() {
height<-10
simple()
}
> foo()
height does not exist
Can somebody please explain why "simple" does not find the "height" variable
when I run it?
Is there an easy way to make R use scoping rules like python where it
searches over all frames to find the value of an symbol?
Thanks, Steve Eick
