Subject:[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.
I would suggest something like this:
library(lme4)
data(sleepstudy)
(fm1 - lmer(Reaction ~ Days + (Days|Subject), sleepstudy))
lmer.coef - fixef(fm1)
# save coefficients columnwise
# keep in mind that dec=, is needed to fulfil the requirements of
my German version of MS-Excel
lmer.out.mat-matrix(lmer.coef,ncol=length(lmer.coef))
write.table(lmer.out.mat,file=d:/lmer_out.csv,sep=;,dec=,,col.na
mes=names(lmer.coef),row.names=F)
# save coefficients rowwise
lmer.out.df-as.data.frame(lmer.coef)
write.table(lmer.out.df,file=d:/lmer_out.csv,sep=;,dec=,,row.nam
es=T,col.names=F)
Is that what you are looking for?
Bernd
