Hi guys,
How to pass an operator to a function. For example,
test <- function(a, ">", b)
{
return(a>b) #the operator is passed as an argument
}
I think you have just requested the definition of do.call() although
you infix positioning is a bit non-standard:
?do.call
> do_this <- function(a, fn=">", b) {do.call(fn, list(a , b))}
> do_this(a=1, b=4)
[1] FALSE
> do_this(a=1, b=0)
[1] TRUE
