Dear R-help,
I'm trying to load the fGarch package and keep running into problems
with tcltk:
After succesfully instaling fGarch (and dependencies) I get:
>library(fGarch)
Loading required package: fBasics
Loading required package: fImport
Loading required package: fSeries
Loading required package: robustbase
Loading required package: fCalendar
Loading required package: MASS
Loading required package: fEcofin
Loading required package: fUtilities
Loading required package: RUnit
RUnit 0.4.17 loaded.
Loading required package: spatial
Loading required package: tcltk
Loading Tcl/Tk interface ... Error in fun(...) : couldn't connect to
display ":0"
Error : .onLoad failed in 'loadNamespace' for 'tcltk'
Error: package 'tcltk' could not be loaded
Then, after checking the OSX faq, I get
>Sys.putenv("DISPLAY"=":0")
Warning message:
'Sys.putenv' is deprecated.
Use 'Sys.setenv' instead.
See help("Deprecated")
But the problem remains:
Sys.setenv("DISPLAY"=":0")
> library(fGarch)
Loading required package: fBasics
Loading required package: fImport
Loading required package: fSeries
Loading required package: fCalendar
Loading required package: fEcofin
Loading required package: fUtilities
Loading required package: tcltk
Loading Tcl/Tk interface ... Error in fun(...) : couldn't connect to
display ":0"
Error : .onLoad failed in 'loadNamespace' for 'tcltk'
Error: package 'tcltk' could not be loaded
I am not sure what the tcltk interface does and what I need it for ...
Also, tcltk is not listed in the package list but tcltk2 is so I'm
not sure which package is being loaded
here?
What can I do about this?
Best, Ingmar
