Yes, segmentation fault.
It only happens when these are *logical*

Using response variable in interaction as explanatory variable in glm crashes R
The following code crashes R (I know I shouldn't try to estimate such a
model; this was a bug in some code of mine). I also tried with R-devel;
same result.
tab <- structure(list(dob_day = c(FALSE, FALSE, FALSE, FALSE, TRUE,
TRUE, TRUE, TRUE), dob_mon = c(FALSE, FALSE, TRUE, TRUE, FALSE,
FALSE, TRUE, TRUE), dob_year = c(FALSE, TRUE, FALSE, TRUE, FALSE,
TRUE, FALSE, TRUE), n =

Out-of-sample prediction with VAR
Good day,
I'm using a VAR model to forecast sales with some extra variables (google
trends data). I have divided my dataset into a trainingset (weekly sales +
vars in 2006 and 2007) and a holdout set (2008).
It is unclear to me how I should predict the out-of-sample data, because
using the predict() function in the vars package seems to estimate my
google trends vars as well. However, I want

using a factor as col argument in plot:
Dear R core team
Using the following code produces an empty plot (similar

> plot(1:9, col = factor(rep(1:3,3), labels = c("red", "blue", "black")))
My question: Shouldn't one get at least a warning (or an error)
if one tries to use a factor as col argument?
Thanks for an answer.

call queue problems
...erating center provide customer care services
for customers who call in after the last customer care staff logs out of the
call queue
During the day time, calls must not (under any circumstances) be routed to
the Network OC for any reasons
My pressent implementation works after hours, when no noe islogged in but
calls still get routed to the NOC during the Day time. This is caused by the
timeout value that i set.
What can i do to remedy this or is there a way to query * if there are
logged on users? (something like CHANISAVAIL apps)
here are some of my configurations!!
This is where calls enter...
