Dear R community,



Below you may find the details of my model (lm11). I receive the error
message "Error: cannot allocate vector of size 220979 Kb" after
applying the autocorrelation function update(lm11, corr=corAR1()).



lm11<-lme(Soil.temp ~ Veg*M+Veg*year,

           data=a,

           random = list(Site=pdDiag(~Veg),

                                   Plot=pdDiag(~Veg))

Dataset:

a-data frame of daily measurements of soil temperature (Soil.temp)
over six years

Site (6 sites),

Plot(2 plots per site),

Veg(2 vegetation types: 2 sites as grassland, 4 sites as forest)

M-month (categorical predictor)

year (continues)



Thanks,

Julia
