as.centcosums: Coerce to a centcosums object.

In shabbychef/fromo: Fast Robust Moments

Description

Convert data to a centcosums object.

Usage

as.centcosums(x, order=2, na.omit=TRUE)

## Default S3 method:
as.centcosums(x, order = 2, na.omit = TRUE)

Arguments

x	a matrix.
order	the order, defaulting to 2.
na.omit	whether to remove rows with NA.

Details

Computes the raw cosums on data, and stuffs the results into a centcosums object.

Value

A centcosums object.

Note

The moment computations provided by fromo are numerically robust, but will often not provide the same results as the 'standard' implementations, due to differences in roundoff. We make every attempt to balance speed and robustness. User assumes all risk from using the fromo package.
