[R] '=' vs '<-'

[Doran, Harold]

Yes, but <- is preferred. Note, there are also some differences. You can do the following:

> a <- 10
> b = 10
> identical(a,b)
[1] TRUE

And you can also do
> myFun <- function(x, y = 100){
+ result <- x*y
+ result}
> myFun(x  = 20)
[1] 2000

But, you cannot use '<-' to define the arguments of a function
