Re: [R] fGarch and is.na()

2008-12-02 Thread Yohan Chalabi 
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

> methods:::bind_activation(TRUE)
> dfr  <- data.frame(matrix(0, nrow = 1 , ncol = 1000))
> dfr2 <- is.na(dfr)

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

regards,
Yohan

[R] fGarch and is.na()

2008-12-02 Thread Felix Lamp 
Hello,

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

> sessionInfo()
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:

> dfr2 <- is.na(dfr)
>

Loading required package: fGarch

I wonder whether this is intended.
