The compress = TRUE causes an errory when using rgd.param from gdxrrw on an empty parameter. Same probably for variables.

library(gamsr)

Load file

gdx = "C:/Daten/Projekte/UNSEEN/data/THG95_2050.gdx"

myselectedcols <- c("ConvBase_CostInfo")

import_gdxfile(gdx, selection = myselectedcols)

He got the following error:
Fehler in source("gdxtext.R") : gdxtext.R:199:245: unerwartetes Symbol
198: arameter'
199: l.all[[40]] <- list(name ='ConvBase_CostInfo', data = ConvBase_CostInfo, description = 'Cost overview, all outputs in kEUR, Caution: specific costs are average values over yearBuild; allInstC

We guess the error occurs due to the unusual length of the explanatory text of the parameter “ConvBase_ConstInfo”. Here its declaration:

PARAMETER ConvBase_CostInfo( nodesModelAll, convBase_technologies, CostInfoSet, years) "Cost overview, all outputs in kEUR, Caution: specific costs are average values over yearBuild; allInstCaps = sum of all power plants which generate or don't generate electricity; totalCaps = sum addCaps + instCaps"

We fixed the issue by simply shortening the explanatory text.

By the way: Thanks for the package!

Hello, I am a Postgraduate student in South China University of Technolog. I have been reading your doctoral thesis Transportation Networks and Economic Equilibrium recently. I am particularly interested in the content of chapter II, A traffic equilibrium model with paid-parking search. I'm trying to implement your appendix code, but my code ability is very poor, and the appendix code you provided did not run through. Now I am about to face my master's thesis, I am so anxious. So, I hope to have your code support(chapter II), thank you.

My email: [email protected] or [email protected]

Best wishes!

Importing a gdx with a ' in a description causesto the following error:

Error in source("gdxtext.R") : gdxtext.R:2479:114: unexpected symbol
2478:  attributes(HARVCOST_SHAREFIXED)$type <- 'scalar'
2479:  l.all[[496]] <- list(name ='HARVCOST_SHAREFIXED', data = HARVCOST_SHAREFIXED, description = 'share of the Georg's

Presumably, some escaping should be done on line 112 of import_gdxfile.R.
