You want lme(logSSP~logM + K,random=~logM + K|species,data=data1)

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

Hi guys, 

Got a few days left and I need to model a random effect of species on the body mass (logM) and temperature (K) slopes. This is what i've done so far that works: 
model1<-lme(logSSP~logM + K,random=~1|species,data=data1) model2<-lme(logSSP~logM + K,random=~K|species,data=data1) model3<-lme(logSSP~logM + K,random=~logM|species,data=data1) 

The one I now want is: 
model4<-lme(logSSP~logM + K,random=~logM|species,K|species,data=data1)
#I need the random effect of spp on both slopes of logM and K, but this code doesn't work so how do i change the code??????

:( Any help will be greatly appreciated
