Description
In-place operations like i += 1, i -= 1 is not support in
R. These functions implement these operations in R.
Usage
inc(e1, e2 = 1)
mult(e1, e2 = 2)
divi(e1, e2 = 2)
Arguments
e1 |
object, most likely a numeric object |
e2 |
the operation value, the value to add, subtract, multiply, divide of. |
Details
inc(i) is the same as i <- i + 1.
inc(i, -1) is the same as i <- i - 1.
mult(i) is the same as i <- i * 2.
divi(i) is the same as i <- i / 2.
Value
No return, directly assign the value back to e1
