Why does the following work in R?
> `:=` <- function(x, y) x + y
> 1 := 2
[1] 3
My understanding was that % was required for user-defined infix operators. Are there other (possibly easier to type) options available?
This is because
:=is, like<-or<<-, defined asLEFT_ASSIGNfor the parser of R.See http://svn.r-project.org/R/trunk/src/main/gram.y
This means that
:=is a special case and you may as well not expect that any other options are available.
