Dear R community,
Here are details of my model, which gives me trouble modeling autocorrelation. 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 > Van: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Namens J S > Verzonden: vrijdag 16 mei 2008 23:06 > Aan: r-help@r-project.org > Onderwerp: [R] autocorrelation in nlme; Error: cannot allocate vector of > size > > Dear R community, > > > > I used a linear mixed model (named lm11) to model daily soil temperature > depending upon vegetation cover and air temperature.
