I run the following code...

Memory allocation problem with large dataset
...ct size of 3605660 bytes. When I try this
second model that involves a correlation structure for the random effects:
vanfemfit2<-update(vanfemfit1, correlation=corAR1())
I receive the following error message:
Error: cannot allocate vector of size 392.9 Mb
In addition: Warning messages:
1: In corFactor.corAR1(object) :
Reached total allocation of 1022Mb: see help(memory.size)
I have looked through all of the R-help archives, but nothing that was

ape comparative analysis query
....8,B2=3.5,B3=3.2,B4=3.5,A1=1.8)
picx<-pic(x,phy=tree)
picy<-pic(y,phy=tree)
Which seems to make sense. However, if I try to use anything more
sophisticated I run into problems:
>dat<-as.data.frame(cbind(x,y))
>model1<-gls(y~x,data=dat, correlation=corBrownian(phy=tree))
Error in corFactor.corStruct(object) : NA/NaN/Inf in foreign function

or equally:
