fGarch and is.na()

Tue, Dec 2, 2008 6:06 AM #

Hello,

after loading package "fGarch" the function is.na.data.frame() is behaving different:

R version 2.8.0 (2008-10-20) 
i386-pc-mingw32 

locale:
LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

Loading required package: fGarch
Loading required package: timeDate
Loading required package: timeSeries
Loading required package: fBasics
Loading required package: MASS

Error: evaluation nested too deeply: infinite recursion / options(expressions=)?

I wonder whether this is intended.

Best,

Felix

Thanks for the report,

the problem boils down to the call of "methods:::bind_activation(TRUE)"
in one of the depended package.

I can reproduce the problem with

I will forward you remark to the R-dev mailing list.
