R: Write R data to GDX

R Documentation

Write R data to GDX

Description

Create a GDX file containing the GAMS data described in the lists .... Note that each list describes a separate data element - i.e. a set or parameter - all of which are written to a single file.

Usage

  # generic form - each arg is a list specifying a symbol to write
  wgdx(gdxName, ..., squeeze = 'y')

  # write multiple symbols specified in list, data frame, or scalar form
  wgdx.lst(gdxName, ..., squeeze = 'y')

Arguments

`gdxName`	the name of the GDX file to write
`...`	zero or more arguments describing the symbols to write. For `wgdx`, each arg must be a list holding a symbol (e.g. as returned by `rgdx)`. For `wgdx.lst`, each arg is also allowed to be a data frame holding a symbol (e.g. as returned by `rgdx.param` or `rgdx.set`), a scalar holding a symbol (e.g. as returned by `rgdx.scalar`), or a list containing any combination of these elements.
`squeeze`	if 'y'/TRUE/nonzero, squeeze out zeros: do not store in GDX. If 'n'/FALSE/zero, do not squeeze out zeros: store explicit zeros in GDX. If 'e', store zeros as EPS in the GDX.

Note

A common problem is failure to load the external GDX libraries that are required to interface with GDX data. Use igdx to troubleshoot and solve this problem.
