I'm confused with the nature of ->, I cannot get its definition like I can with other operators and it doesn't behave like <-. See below:
print(`<-`) # .Primitive("<-")
print(`->`) # Error in print(`->`) : object '->' not found
Also, I can't hijack it, though R won't fire any error if I try to :
`->` = `+` # attempting to hijack `->`, no error
print(`->`) # function (e1, e2) .Primitive("+"), seems like it worked
1 -> 3 # Error in 3 <- 1 : invalid (do_set) left-hand side to assignment
1 -> test1
print(test1) # 1, hijacking failed
`->`(1,3) # 4, this works
With <- (or any other operator I tried), I can do it:
`<-` = `+`
print(`<-`)
1 <- 3 # 4
1 <- test2 # Error: object 'test2' not found
rm(list=ls()) # back to sanity
So what's going on ?
