Inserts new values into a vector at specified positions

This function inserts new values at specified positions in a vector. It does not replace existing values. If a single value is provided for y and l represents multiple positions y will be replicated for the length of l. In this way you can insert the same value at multiple locations.

insert.values(x, value, index)

Arguments

x

A vector to insert values

value

Values to insert into x

index

Index position(s) to insert y values into x

Value

A vector with values of y inserted into x and the position(s) defined by the index

Examples

(x=1:10)
#> [1] 1 2 3 4 5 6 7 8 9 10
# Insert single value in one location insert.values(x, 100, 2)
#> [1] 1 100 2 3 4 5 6 7 8 9 10
# Insert multiple values in multiple locations insert.values(x, c(100,200), c(2,8))
#> [1] 1 100 2 3 4 5 6 200 7 8 9 10
# Insert single value in multiple locations insert.values(x, NA, c(2,8))
#> [1] 1 NA 2 3 4 5 6 NA 7 8 9 10
