Re: [R] Nested variance-covariance matrix in Multilevel model

What's your error message? I see a syntax error in random=list(Probe=pdBlocked(list(~1,pdCompSymm(~1 ),End=~1,ProbeNo=pdCompSymm(~1)) I count 5 open parens and 3 close parens. I know that might have been part of what you copied into this email and not what you gave R.

[R] Nested variance-covariance matrix in Multilevel model

2006-06-19 Thread Tobias Guennel
Dear R community, I have trouble implementing a nested variance-covariance matrix in the lme function. The model has two fixed effects called End and logpgc, the response variable is the logarithm to base 2 of Intensity ( log2(Intensity) ) and the random effects are called Probe and ProbeNo.

I completely forgot to supply the R code I tried: vov1i2-read.table(VOV1_INHIBITED6-16-2006-13h35min33sec.txt,header=TRUE) test.lme-lme(fixed=log2(Intensity)~End+logpgc,random=list(Probe=pdBlocked(list(~1,pdCompSymm(~1 ),End=~1,ProbeNo=pdCompSymm(~1)),data=vov1i2) It doesn't look right to me
