What are the differences between the assignment operators
<- in R? R中赋值运算符
I know that operators are slightly different, as this example shows 我知道运算符略有不同，如本例所示
x <- y <- 5 x = y = 5 x = y <- 5 x <- y = 5 # Error in (x <- y) = 5 : could not find function "<-<-"
But is this the only difference? 但这是唯一的区别吗？
