R: Using "biglm" with "matter"

biglm {matter}

R Documentation

Using “biglm” with “matter”

Description

This method allows matter_mat matrices and matter_df data frames to be used with the biglm and bigglm functions from the “biglm” package.

Usage

## S4 method for signature 'formula,virtual_df'
biglm(formula, data, weights = NULL, sandwich = FALSE)

## S4 method for signature 'formula,virtual_df'
bigglm(formula, data, ..., chunksize = NULL)

## S4 method for signature 'formula,matter_mat'
bigglm(formula, data, ..., chunksize = NULL, fc = NULL)

## S4 method for signature 'formula,sparse_mat'
bigglm(formula, data, ..., chunksize = NULL, fc = NULL)

## S4 method for signature 'formula,virtual_mat'
bigglm(formula, data, ..., chunksize = NULL, fc = NULL)

Arguments

`formula`	A model `formula`.
`data`	A `matter` matrix with column names.
`weights`	A one-sided, single-term formula specifying weights.
`sandwich`	If `TRUE`, compute the Huber/White sandwich covariance matrix (uses `p^4` memory rather than `p^2`).
`chunksize`	An integer giving the maximum number of rows to process at a time. If left `NULL`, this will be calculated by dividing the `chunksize` of `data` by the number of variables in the formula.
`fc`	Either column indices or names of variables which are factors.
`...`	Additional options passed to `bigglm`.

Value

An object of class bigglm.

Examples

set.seed(1)

x <- matter_mat(rnorm(1000), nrow=100, ncol=10)

colnames(x) <- c(paste0("x", 1:9), "y")

fm <- paste0("y ~ ", paste0(paste0("x", 1:9), collapse=" + "))
fm <- as.formula(fm)

fit <- bigglm(fm, data=x, chunksize=50)
coef(fit)
