...r both 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.

...e trick but for some reason, especially when my model has many terms in it or when one of the independent variables is only significant when the other independent variables are in the equation, it gives me strange lines.

...umns could be adjusted or didnt default to the size of the name of the column. (since the names might often be very big if the data frame was created using a function). Side-ways scrolling is quite "jerky" too. Just wondered if this was on anyone else's wish list? Simon.

...d","field","river") )) Is there an eloquent, efficient way of doing this? My solution involves lots of intermediate aggregated data frames, one for each habitat, then a series of merges onto a bigger data frame. Thanks peeps and have a good weekend, Simon.

We're trying to setup 3 PRDM partitions (VMware) across 2 nodes. As long as only one is configured in cluster.conf, there's not problem. As soon as we try to use 2 or more we get issues. It looks the same as bug 636: http://oss.oracle.com/bugzilla/show_bug.cgi?id=636 I posted my cluster.conf and command line results there. I'm including them here in the hopes that someone on this

Dear users, a very simple question: Given two vectors x and y x<-as.character(c("A","B","C","D","E","F")) y<-as.factor(c("1","2","3","4","5","6")) i want to combine them into a single vector z as A1, B2, C3 and so on. z<-x*y is not working, i tried several others

Asterisk must have a reasonably large community here in France judging from the number of people who came out to meet Mark. Either that or we were ALL there :) Something I've been waiting for, a voIP carrier on the models we are used to (low monthly or pay as you go, web account) has just set up their first beta test for 1 euro for the first month, 6euros if you decide to keep it. The basic

...f each session and have each new graphic device overwrite the previous one. I only know how to do this using windows(width=,height=...) which opens up a new plotting device every time, so I end up with lots of graphs all over the place until I get the one I want!

...mmand wont work. Does anyone have any 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...

...two parameters as well as using the simple linear regression on each individual separately, as judged by looking at graphs. Indeed, why do the results differ at all?

...for each individual so I use coef(m1) to get 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))....
