Dear R users,
Hopefully someone can help me,
Maybe I just misunderstand the function in the package?
I am working with a logistic regression model.
Until now I always worked with the basic glm function, where for the model
was:
¡§ glm( disease ~ test.value + cnct ,
Dear useR's,
I was comparing results for a logistic regression model between different
library's.
themodel formula is arranged as follows:
response ~ (intercept) + value + group
OR:
glm( response ~ (intercept) + value + group ,
family=binomial(link='logit'))
lrm( response ~
Hi all,
I was working with the MEMSS mle4 library's under R version 2.15.1.
apparently some practical functions of do not work under R 2.15.1.
After searching the archives i found a mail thread on this subject,
stating that these problems were partialy solved for R 2.12.0 but only
for lmer()
Dear R users,
My question is about finding the proper font size for graphics.
For this i had written a code that creats 4 diferent graphics and saves
them as a png file.
From these PNG.graphics , i select one of the proper size and past it to a
word document.
I have experimented with lots of

Dear R-users,
I'm having a small problem while bootstraping data.
What i would like to do, is resmple the data and calulate a function on
this, so i can estimate the measure of reproducability for this data.
The function i wrote works fine, even while bootstraping.
The only problem is that
Dear R users,
I 'm having problems with creating PNG graphic outputs.
Usualy i create reports in HTML format, containing PNG graphics, so they
can ealsaly be exported to word and xl and so on.
On a windows pc that i use at work all works fine, but it never works on
my mac.
The HTML's i create
Dear R ussers ,
I was trying to summaryse data with sql, from the sqldf pkg.
it seemed like a promessing solution, yet all i can do in this is
calculate avg count and sum.
where i d like to use confidence intervals and standard deviation as wel.
now i was trying to find a solution my
Dear R-ussers,
I would like to save a newly created data file, out of R in to a text
file.
It is a rather big dataset, and recalculating the new variables takes a
long time.
The quickest way to read data is when it is saved as .txt,
this is why i hope to read the data from the old txt, than
dear R-ussers,
I would like to creeate a graph, i wich my data is presented as verticaly
oriented histograms, wich give the frequency of the measured values,
grouped per used measurement methode.
So the X axis should hold the grouping variable and the Y axis a continuos
variable. well not
Dear R-ussers,
While looking for a way to calculate the association between a countinuous
and a binary variable,
i found a procedure called point biserial corralation.
Me, not being a mathematicion, i did my very best to understand what it
was all about, and then i found a easily
Dear Jonh,
there is probably an easier way, but i find this to give nice smooth
plots.
good luck with it.

Hello dear Russers,
I have noticed that certain verry handy functions, like plotMeans and
ci.plot,
only run under Rcmdr.
Rcmdr does not run on a mac , so i hope someone out there knows about an
Rcmdr module for mac's.
Kind regards,
Tom

Dear R ussers,
I noticed a small problem when ussing for example the function
plotMeamns under Rcmdr.
In this case a graph will be ploted, giving the means on the Y-axis, by a
factor on the X-axis.
All is correct when doing this, ussing 'sd' for error bars.
The problem occures when ussing
