naExcludeMvr function

Adjust for Missing Values

Use missing value information to adjust residuals and predictions. This is the mvr equivalent of the naresid.exclude and napredict.exclude functions.

naExcludeMvr(omit, x, ...)

Arguments

• omit: an object produced by an na.action function, typically the "na.action" attribute of the result of na.omit or na.exclude.
• x: a three-dimensional array to be adjusted based upon the missing value information in omit.
• ...: further arguments. Currently not used.

Returns

x, padded with NAs along the first dimension (rows ).

Details

This is a utility function used to allow predict.mvr and residuals.mvr to compensate for the removal of NAs in the fitting process.

It is called only when the na.action is na.exclude, and pads x with NAs in the correct positions to have the same number of rows as the original data frame.
