LinkedMatrix is an R package that provides matrices implemented as lists of matrix-like nodes, linked by columns or rows.

It was originally developed for the [BGData](https://CRAN.R-project.org/package=BGData) package to address the array size limit of [ff](https://CRAN.R-project.org/package=ff) (`length must be between 1 and .Machine$integer.max`) by chaining multiple `ff` objects together.

This package is deliberately kept simple. For computational methods that use LinkedMatrix check out the [BGData package](https://CRAN.R-project.org/package=BGData).

Example

-------

The following code generates three different matrix-like objects and links them together by rows in a `RowLinkedMatrix`. The `LinkedMatrix` instance can then be treated like any other regular matrix.

```R

library(LinkedMatrix)

m1 <- ff::ff(initdata = rnorm(50), dim = c(5, 10))

m2 <- bigmemory::big.matrix(init = rnorm(50), nrow = 5, ncol = 10)

m3 <- matrix(data = rnorm(50), nrow = 5, ncol = 10)

m <- RowLinkedMatrix(m1, m2, m3)

dim(m)

m[1, ]

m[, 1]

```

Installation

------------

Install the stable version from CRAN:

```R

install.packages("LinkedMatrix")

```

Alternatively, install the development version from GitHub:

```R

# install.packages("remotes")

remotes::install_github("QuantGen/LinkedMatrix")

```
