Standardize x and y vectors to achieve zero mean and unit variance.

stdz_xy(x, y)

Arguments

• x: Vector of data which can have NA's
• y: Vector of data which can have NA's

Returns

• stdx: standardized values of x

• stdy: standardized values of y

Note

This works even if there are missing x or y values.

Examples

## Not run:

set.seed(30)
x=sample(20:30)
y=sample(21:31)
