⚠️There's a newer version (0.6.11) of this package.Take me there.

matsbyname

The R package matsbyname enables matrix mathematics wherein operations are performed “by name” and row and column types are allowed.

Installation

You can install matsbyname from CRAN with:

install.packages("matsbyname")

You can install a recent development version of matsbyname from github with:

# install devtools if not already installed
# install.packages("devtools")
devtools::install_github("MatthewHeun/matsbyname")
# To build vignettes locally, use
devtools::install_github("MatthewHeun/matsbyname", build_vignettes = TRUE)

History

The functions in this package were used in Heun et al. (2018).
