Is there any R can i install in ubuntu which runs in hos own prompt or
terminal??
Thanks

send commands from script to console
Hi,
I'm working with R in windows and I wonder if there is any command (of the
kind CTRL+ ) to transfer the commands I've worked with (like: >
model<-glm(prevalencia~edadysexo*mes*zona,binomial)) to a script
automatically, without the results I received from R after execute them.
Another question, what's the combination of CTRL+ for transfer the orders in

Changing labels positions in two graphics
Hi,
I?ve got some problems with the labels of the x-axis
I,ve got two factors with two categories each: sex (males and females) and
area (central and peninsulae),
but because of the lenngth in the graphic just appeared two of the four
labels.
I thought the solution could be rotate it 45? degrees, I have read it can be
done with "srt" or "rotate", but I don?t know hoe to use

Hi,
I'm trying to make a model in order to know wich factors got?s influence in
the intensity of a infection, but just in the individuals who's got this

kruskal wallis post hoc?
Dear all,
I run a kruskal wallis test and found significant results. Then, I conducted all pairwise comparisons and found no significant results. Could anyone please give me a hint as to why this happens or redirect me towards a specific web page where I can find more info? (I used alpha=5% and made no bonferroni or other correction for the pairwise comparisons)
Thank you

R2wd package wdGet() error
I am having trouble using the R2wd package. The last time I used it
successfully, I was running an earlier version of R and an earlier version
of Word with an earlier Windows OS. I'm not sure which if any of these
changes might be contributing to the problem. Right now I'm using
R version 2.15.0 (2012-03-30) for Windows
MS Word 2010 version 14.0.6112.5000 (32-bit)

GLM different results with the same factors
I've read something about this problem, but I don't know how can i avoid this
problem.
Why the order of the factors give different results? I suppose it's because
the order of the factors, i've just changed "lcc" from the first position to
the last in the model, and the significance change completely

Looking for Filliben (correlation test)
Hi R-users,
I need to run Filliben correlation test, but I'm not able to find this
function in any package.
Perhaps it isn't in a package, but sometimes anybody have program this
function or create a routine to estimate it.
I found it in google and I hope what I found it's in this page,
http://genepi.qimr.edu.au/staff/davidD/R/filliben.R
but i can't open it.
Anybody can help me?
