segfault with correlation structures in nlme
...segfault errors (which I don't know what they exactly mean =/).
I was wondering if it was an effect of the model or the data I used, but
I was able to reproduce the error messages using the Ovary data set and
the example in the Pinheiro & Bates book:
>library(nlme)
>data(ovary)
>fm10var.lme <- lme(follicles ~ sin(2 * pi * Time) +
cos(2 * pi * Time),data=Ovary,
random=pdDiag(~sin(2*pi*Time)))
>fm50var.lme <- update(fm10var.lme,correlation=corARMA(p=1,q=1))
>fm10var.nlme <- nlme(follicles ~ A + B * sin(2 * pi * w * Time) +...
