For-Statement

The for-statement executes the statements enclosed in braces N times, where N is the number of values in vector-expression. Each time the statements are executed variable is set to the kth value of vector-expression, where k = 1… N.



for ( variable in vector-expression )
{
statements
}

> for ( i in 1:3 ) { i }
 i =
        1
 i =
        2
 i =
        3

vector-expression can be any type of vector: real, complex, and string vectors are all acceptable.
