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.
# generic form - each arg is a list specifying a symbol to write
wgdx(gdxName, ...)
# write a data frame - inverse of \code{rgdx.param} and \code{rgdx.set}
wgdx.df(gdxName, df)
# write a scalar - inverse of \code{rgdx.scalar}
wgdx.scalar(gdxName, s)
# write multiple symbols
wgdx.lst(gdxName, ilst)
gdxName |
the name of the GDX file to write |
... |
zero or more lists describing the sets and parameters to write |
df |
data frame to write to GDX |
s |
scalar to write to GDX |
ilst |
list of inputs, each of which can be a data frame as
returned by rgdx.param or rgdx.set, a scalar as
returned by rgdx.scalar, or a symbol list as required for
input to wgdx |
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.
The routines wgdx.df and wgdx.scalar are experimental
and perhaps temporary. Don't use them for production work.
