[R] R crash

[Ivan Calandra]

Dear users,

I have already sent this email last week, but haven't received an 
answer. So here is my second try.

By running the script below, R crashes systematically at the last 
command, namely dev.off(), on Windows 7, but not on Windows XP.
I therefore don't provide a reproducible example and do not really 
extract the relevant parts of the script because it has most likely 
nothing to do with the script itself. I can do it though if you think it 
might be relevant.

R crashes on Windows 7, sessionInfo():
R version 2.13.1 (2011-07-08)
Platform: i386-pc-mingw32/i386 (32-bit)
locale:
[1] LC_COLLATE=German_Germany.1252  LC_CTYPE=German_Germany.1252
[3] LC_MONETARY=German_Germany.1252 LC_NUMERIC=C
[5] LC_TIME=German_Germany.1252
attached base packages:
[1] splines   stats     graphics  grDevices utils     datasets  methods
[8] base
other attached packages:
[1] doBy_4.4.0         MASS_7.3-13        snow_0.3-7         
lme4_0.999375-41
[5] Matrix_0.9996875-3 lattice_0.19-30    multcomp_1.2-7     
mvtnorm_0.9-9991
[9] R2HTML_2.2         survival_2.36-9    RSvgDevice_0.6.4.1 R.utils_1.7.8
[13] R.oo_1.8.1         R.methodsS3_1.2.1
loaded via a namespace (and not attached):
[1] grid_2.13.1   nlme_3.1-101  stats4_2.13.1


But it works perfectly on Windows XP, sessionInfo():
R version 2.13.1 (2011-07-08)
Platform: i386-pc-mingw32/i386 (32-bit)
locale:
[1] LC_COLLATE=English_United States.1252
[2] LC_CTYPE=English_United States.1252
[3] LC_MONETARY=English_United States.1252
[4] LC_NUMERIC=C
[5] LC_TIME=English_United States.1252
attached base packages:
[1] splines   stats     graphics  grDevices utils     datasets  methods
[8] base
other attached packages:
[1] doBy_4.4.0         MASS_7.3-14        snow_0.3-6         
lme4_0.999375-41
[5] Matrix_0.9996875-3 lattice_0.19-33    multcomp_1.2-7     
mvtnorm_0.9-9991
[9] R2HTML_2.2         survival_2.36-9    RSvgDevice_0.6.4.1 R.utils_1.7.8
[13] R.oo_1.8.1         R.methodsS3_1.2.1
loaded via a namespace (and not attached):
[1] grid_2.13.1   nlme_3.1-102  stats4_2.13.1

Except the locale, I don't see any difference and I don't really 
understand how that would make R crash by running dev.off(). I would 
guess that the problem comes from RSvgDevice on Windows 7. Can someone 
help me to solve this issue?

Thank you for your help,
Ivan

   two_reg(dat=select, xvar=ind.xvar, yvar=k)
}

dev.off()
