This is generally a locale problem, specifically, LC_CTYPE needs to be
set so that (AFAIR) isprint() returns true on the printable characters
in Hungarian locale. Actually, most of the iso-8859 locales will do
(Does Hungarian use iso-8859-1 or -2, BTW?), e.g. for me

> d$crude.inc<-d$esetszám/d$évközepi.lélekszám*1000000
Error: Object "d" not found
> Sys.getenv("LC_CTYPE")

(NB: no syntax error in that, just a complaint that I didn't define
d). A fair guess is that you want to set 

export LC_CTYPE=hu_HU 

in your .profile, or systemwide wherever SuSE wants you to put it. You
can also set LANG or LC_ALL, although I choose not to because it
upsets other parts of the system (error messages, collating sequence,
