Using response variable in interaction as explanatory variable in glm crashes R
...bles, not, e.g., when
transformed to integer.
The C code in src/library/stats/src/model.c tries to eliminate
occurances of the LHS of the formula from the RHS when building
the model matrix and it does work fine in the integer case.
Part of the culprit code may be this (from line 717),
with the isLogical(.) which in our case, shifts the pointer by
1 in the call to firstfactor() :
int adj = isLogical(var_i)?1:0;
// avoid overflow of jstart * nn PR#15578
firstfactor(&rx[jstart * nn], n, jnext - jstart,
REAL(contrast), nrows(contrast),
ncols(contrast), INTEGER(var_i)...

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 =

Some context:
For my Master's thesis I'm using R to test the predictive power of web
metrics (such as google trends data & pageviews) in sales forecasting. To
properly assess this, I employ a simple AR model (for time series without
the extra variables) and a VAR model for...

using a factor as col argument in plot:
Dear R core team
Using the following code produces an empty plot (similar
to col = NA):
> 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 ent...
