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 package to address the array size limit of 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.
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.
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]Install the stable version from CRAN:
