Opendap won't work on Windows CRAN build of ncdf4, though the rgdal build
does work directly on grib.
Summary: download the files wholus for use on Windows, or set your own
system on Linux.
Building ncdf4 on Windows is not too hard if you know about doing that.

Hello R-experts,
I am interested to determine if the ratio of counts from two groups differ
across two distinct treatments. For example, we have three replicates of
treatment A, and three replicates of treatment B. For each treatment, we have
counts X from one group and counts Y from another

Christofer,
I do not really use the xlsx package, so this may not be the 'best' approach.
And based on your spreadsheet, and the code that you supplied, I am not sure
what you really intended. But here is some sample code that will update cells
in your spreadsheet without changing the

You can't if I understand correctly: there is no individual subject
regression coefficient, only a variance component for a random subject
intercept. Do you mean that you want to "test" whether that component
is nonzero ?(It is, of course). If so, IIRC, lmer eschews such tests
for technical

I have an lmer logistic regression with a within subjects IV and subject as
a random factor:

significantly different from 0.

Dear Anonymous,
It's seems like that package never made it to CRAN. You should contact the
package author or the author of the reference.

The only google hit appears to be that paper, which is a 2014 PhD
dissertation, and states that the author will be uploading it on CRAN.
Since that hasn't been done, the only thing you can do is try to track
down the author and ask.

Hi Paul,
Do you want to avoid using prop.table(mtcars_xtab, 1) ?
If not, how about:
ggplot(as.data.frame(prop.table(mtcars_xtab, 1)))+
geom_bar(aes(x=Var2,y=Freq,fill=Var1), stat="identity", position="dodge")+
scale_fill_brewer(palette="Set2")
Ron.
Many thanks Ista and Bert for your nice solutions!
As Ista commented in a previous mail, the 0.87 value in my example is not
fixed, but for each subject
it depends on the difference "2007-01-01 - fini". However, both of your
solutions take into account this
fact.

No la estás asignando a nada.
