Hi, Is it possible to create Rose Diagrams of wind data (speed & direction) with R??

...the covariances? Or, alternatively, is there a better way to go about this sort of repeated measures analysis in R? I've exhausted my available R resources and done a pretty good search of the help archives without finding a clear answer. Thanks much!

I just detected R and have, after browsing the manual, one question: I look for quite a lot of time for graphical software which allows to plot data from a table or external file _with the axes of the coordinate system changed_, i.e. the x-axis should run from top left to bottom left, and the y-axis from top-left to top-right. It is of no use to interchange the rows in the table, the

Hello, I've got a big problem. I'm using R for geostatistical analyses, especially the field-package. I try to generate plots after the kriging process with help of image.plot(..., col=terrain.colors, ...). Everything works fine, but I want to reverse the color-palettes (heat.colors, topo.colors or gray()) to get darkest colors at highest data-values instead the other way round. Could

...1 Is there a way to find out length(col) (BTW, does col=color?) so that I can readjust the label locations (at=...), or have I completely missed something obvious that would quickly fix this up?

Dear all, I've got a big problem. I try to analyse my data using R with a mixed model ANOVA without useful results and success. My data are as follows: 3 factors (Treatment, Site, Subsite) with 'Subsite' as random factor and nested into 'Site'. I want to analyse the effects of the three main effects (factorial design to a specified degrees (2)) with the interactions between

Hi Kurt, I have started to look into this, and I need some guidance about how to prioritize my repairs. There are basically 4 categories of warnings from gfortran?s pedantic critique of my packages: 1. Some errant tab characters it doesn?t like, 2. Too many or too few continue statements 3. Horrible (and obsolescent) arithmetic and computed gotos 4. undeclared doubles and dubious

Hi all, we found, that R is not only *the* superior data analysis, graphics and statistics package, but it is also a general tool for implementing, running and teaching ecological models. Last week we held our second course "Modelling in Limnology" using R. Some material (code and docs) was produced for this purpose and may be interesting to someone else, so I put the tutorial "Konstruktion ?kologischer Modelle mit der Open Source Software R" on my homepage. The tutorial covers * a short introduction, * some simple regress...

Any insight you may have into the matter would be greatly appreciated. Thanks! ? -- Bryan Althouse Graduate Student UW-Madison Center for Limnology

First, I am really liking what I have seen so far in R. The demos are quite fascinating, and I look forward to doing some really neat stuff over the next little while with R. Being but an intiate to R, I am having quite a bit of trouble figuring out how to use the leaps library. Rather than ask several questions to the list at large, I would rather explain what I'm trying to do to someone in

LQS didn't quite seem what I was looking for. Any pointers are greatly appreciated. Thanks, Pete -- Pete St. Onge - McGill U.

Dear all, I didn't find any graphical solution in the package "mva" to plot the canonical scores from a CCA (canonical correlation analysis). Does anybody knows how to plot or has anybody already programmed : - the map of the canonical scores, - the graph of the canonical weights, - the correlation circle i.e. the canonical loadings ? Thank you for help ...
