This is a library of functions that can be used to read native TransCAD files
directly into R without intermediate conversion to .csv or .dbf. Currently
the package will read and write binary data tables (including network
attributes), but I hope to extend the package to cover shape data and networks
in the future.
The package is not (yet) on CRAN. The easiest way to install the latest stable version is with
devtools::install_github("wsp-sag/tcadr")Using the devtools library may require you
to install RTools and Rccp, among other things.
