Simply read it in using `readRDS(file)`.
I?m trying to setup a GLMM using the `glmmPQL` function from the `MASS`
package including a random effects part and accounting for spatial
autocorrelation. However, R (Version: 3.3.1) crashes upon execution.
library(nlme)
# setup model formula
fo <- hail ~ prec_nov_apr + t_min_nov_apr + srad_nov_apr + age
# setup corSpatial object
correl = corSpatial(value = c(10000, 0.1), form = ~ry + rx, nugget
= TRUE,
fixed = FALSE, type = "exponential")
correl = Initialize(correl, data = d)
# fit model
fit5 <- MASS::glmmPQL(fo, random = ~1 | date, data = d,
correlation = correl, family = binomial)
What I tried so far:
- reduce number of observation
- play with `corSpatial` parameters (range and nugget)
- reduce number of fixed predictors
- execute code on Windows, Linux (Debian) and Mac R installations
While I get no error message on my local pc (RStudio just crashes),
running the script on a server returns the following error message:
`R: malloc.c:3540: _int_malloc: Assertion (fwd->size & 0x4) == 0'
failed. Aborted`
Debugging leads me to a "glibc" c++ library problem. I also run valgrind
on it. If you need the output, just ask!
Help ist highly appreciated!
Cheers, Patrick
