block.data.frame: Block-wise indexable data.frame

Description

This is a convenience function for making data.frames that are easily indexed on a block-wise basis.

Usage

block.data.frame(X, block_inds = NULL, to.matrix = TRUE)

Value

A data.frame which can be indexed block-wise.

Arguments

X

Either a single data.frame to index or a list of matrices/data.frames

block_inds

Named list of indexes if X is a single data.frame, otherwise NULL.

Examples

# Random data
M <- matrix(rnorm(200), nrow = 10)
# .. with dimnames
dimnames(M) <- list(LETTERS[1:10], as.character(1:20))

# A named list for indexing
inds <- list(B1 = 1:10, B2 = 11:20)

X <- block.data.frame(M, inds)
str(X)
