Read item from .gdx file as quitte data frame

read.gdx() is a wrapper function for either gdxrrw::rgdx() or gamstransfer::readGDX() that returns a quitte data frame.

Usage

read.gdx(
  gdxName,
  requestList.name,
  fields = "l",
  colNames = NULL,
  factors = deprecated(),
  squeeze = TRUE
)

gdxName: Path to a .gdx file.
requestList.name: Name of the item to read.
fields: Fields to read from variables and equations. When using gdxrrw, any of l, m, lo, up, s. When using using gamstransfer, level, marginal, lower, upper, and scale are understood as well. all will return all fields. Ignored when reading sets or parameters.
colNames: String vector of column names to override dimension and field names.
factors: Deprecated. Do not use any more.
squeeze: If TRUE, squeeze out any zero or EPS stored in the GDX container. Ignored when using gamstransfer.

A quitte data frame.

read.gdx() will use gdxrrw::rgdx() if gdxrrw is installed and the option quitte_force_gamstransfer is not TRUE, otherwise it will use gamstransfer::readGDX().
