Assignment Operators
These operators are used to assign values to vectors.
| Operator | Description | Example |
|---|---|---|
|
<− or = or <<− |
Called Left Assignment | a1 <- c(3,1,TRUE,2+3i) a2 <<- c(3,1,TRUE,2+3i) a3 = c(3,1,TRUE,2+3i) print(a1) print(a2) print(a3) it produces the following result − [1] 3+0i 1+0i 1+0i 2+3i [1] 3+0i 1+0i 1+0i 2+3i [1] 3+0i 1+0i 1+0i 2+3i |
|
-> or ->> |
Called Right Assignment | c(3,1,TRUE,2+3i) -> a1 c(3,1,TRUE,2+3i) ->> a2 print(a1) print(a2) it produces the following result − [1] 3+0i 1+0i 1+0i 2+3i [1] 3+0i 1+0i 1+0i 2+3i |
More Eamples
The operators <- and = can be used, almost interchangeably, to assign to variable in the same environment.
The <<- operator is used for assigning to variables in the parent environments (more like global assignments). The rightward assignments, although available are rarely used.
> x <- 5
> x
[1] 5
> x = 9
> x
[1] 9
> 10 -> x
> x
[1] 10
