Dear list members, I am writing some functions to help with printing graphs. If I want to return the name of a variable within a function, for instance to print the label for a graph, I know that I can use substitute: fun=function(x) substitute(x) #plus of course some other processing var=1:3 fun(var) #prints "var" as required, not "x".
But if I call this function in another function fun2=function(y) fun(y) #plus of course some other processing fun2(var) #prints "y" when what I wanted was "var" I have tried lots of tricks using eval and expression but can't seem to get it right. Any ideas?
