mat: Matrices

Description

Like matrix, mat creates a matrix from the given set of values. However, these values can also be represented by a character string, or a list of vectors.

Usage

mat(x, ...)
"mat"(x, ...)
"mat"(x, rows = TRUE, sep = getOption("mat.sep"), ...)
"mat"(x, rows = TRUE, ...)

Arguments

x

A data vector, character string, or a list.

...

Aditional optional arguments.

rows

Logical. If TRUE (the default) the matrix is filled by rows, otherwise the matrix is filled by columns.

sep

Separator string. Values within each row/column of x are separated by this string. Default is ",".

Value

A matrix of class c("matrix", "mat").

Examples

## Using character vectors
mat("1, 2, 3, 4; 5, 6, 7, 8")  # ";" separates rows
mat("1, 2, 3, 4; 5, 6, 7, 8", rows = FALSE)  # ";" separates columns
mat("1 2 3 4; 5 6 7 8", sep = "")  # use spaces instead of commas
mat(c(1, 2, 3, 4, 5, 6, 7, 8), nrow = 2, byrow = TRUE)  # works like matrix too

## Using a list
z1 <- list(1:5, 6:10)
z2 <- list(a = 1:5, b = 6:10)
mat(z1)
mat(z2)  # preserves names as row names
mat(z2, rows = FALSE)  # preserves names as column names
