[R] percentage explained by fixed effects in random model

Hi, I realise this has come up before in various reincarnations but I couldnt find the answer... I wish to quote the percentage variance explained by each of three components in my mixed model. If I didnt have a random effect I would just use r squared. I can work out the percentage explained

Re: [R] graph dimensions default

Yes, Thankyou, that does the trick nicely. I thought that kind of thing could be specified using par() but I guess not. Thanks again. On Tue, 14 Aug 2007, Simon Pickett wrote: Hi, I would like to (if possible) set the default width and height for graphs at the start of each session

[R] arrows and points for error bars

solutions to this problem, or maybe even a different way of making error plots? Sorry if this seems a bit pedantic, but it would be great if I could resolve this problem and so enable me to use R for publication standard graphs... Thanks everyone :-) Simon Pickett PhD student Centre For Ecology

Re: [R] REML with random slopes and random intercepts giving strange results

, Simon I don't this is because you are using REML. The BLUPs from a mixed model experience some shrinkage whereas the OLS estimates would not. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Simon Pickett Sent: Tuesday, August 15, 2006 11:34 AM

at graphs. Indeed, why do the results differ at all? Excuse my naivety if this is a silly question. Thanks to everyone for replying to my previous questions, very much appreciated.

[R] help: convert lmer.coef to matrix

Hi all, I am trying to coerce the coeficients from a REML using lmer() to a matrix of numbers which I can then write into excel. I have looked in the archive and read around in the (Matrix) documentation but havent found anything of use. Any suggestions much appreciated, Thankyou, S. Simon

[R] help:coerce lmer.coef to matrix

this which results in an object of class lmer.coef, 3 columns by 700 rows. as.data.frame() wont work on this and I cant seem to specify that I want three columns when I tried -matrix(lmer.coef,ncol=length(lmer.coef)) Thanks very much, S Simon Pickett PhD student Centre For Ecology

[R] help with structuring random factors using lmer()

x1 and x2 (a coefficient score for every individual). m1-lmer(weight~time+timesq+(1|id)+(timesq-1|id)+(time-1|id), data=dataset) coef(m1) gives me nearly what I want except there isnt an individual coefficient score for each individual for x2. Any suggestions very much appreciated. Simon Pickett
