R help - Jun 2004 - Modifying Code in .rda based packages (e.g. lme4)

Dear List,

assume I want to make a minor local change in a package that is supplied as
.rda. For example, I want to get rid of the non-verbose-protected
"Iteration" message in GLMM/lme4.

Probably I have to load / change / save the package, but could someone help
me to get the syntax right?

No standard R package is supplied as a .rda, including not lme4.  You
must be looking at a binary installation, and you would do best to
reinstall from the sources.  You could use

R --vanilla
load("..../all.rda")
fix(GLMM)
save(ls(all=T), file="..../all.rda", compress = TRUE)
q()

but we would not recommend it.  Indeed, we do not recommend your altering
functions in other people's packages.  Why not just make a copy of GLMM
with another name and alter that?

You should probably download the source for the package from CRAN, 
modify the source, then reinstall.

Brian Ripley already replied on how to change the code.  

I just wanted to say that we will add verbose protection to the
Iteration messages in GLMM/lme4.
