The unit US$2005/(tCO2/yr) breaks the magclass unit convention, which does not support nested parentheses. Specifically

library(remind)
library(quitte)

a <- convGDX2MIF(gdx = './tests/testgdxs/fulldata.gdx')

as.quitte(a)
Error in magclass::`getNames<-`(`*tmp*`, value = sub(" \\(([^\\()]*)\\)($|\\.)",  : 
  Inconsistent names! Number of dots per name has always to be the same as it is separating different data dimensions
In addition: There were 21 warnings (use warnings() to see them)
