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

Hello- I'm trying to do some repeated measures ANOVAs. In the past, using SAS, I have used the framework outlined in Littell et al.'s "SAS System for Mixed Models", using the REPEATED statement in PROC MIXED to model variation across time within an experimental unit. SAS allows you to specify different within-unit covariance structures (e.g., compound symmetric, AR(1), etc.) to

...nal 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 coordinate system should rely of that definition. This type of plot is used in limnological and oceanological graphs. Until now I could find no software which can do that job. Perhaps one of you can answer this beginner's question with a simple yes or no? Thank you, Richard -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read...

...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 anyone give me hints or some syntax to resolve that problem??

Dear R'ers, I've scanned available documentation and the web, but I can't seem to figure out where I've gone wrong in adding numbers to scale the colorkey in levelplot (Lattice package). For example, levelplot(z, contour=T, labels=T, cuts=10, region=T,... colorkey=list(T, space="bottom", at=seq(0,2000,length=20),

Hi all- Some recent change...perhaps a windows update, or perhaps a change in the network on which I use my computer....has made it impossible for me to start R. When I try to start the program, I get a message that says "Fatal error: invalid HOMEDRIVE". Any ideas on how to fix this? Thanks much Chris ******* Chris Solomon Center for Limnology Univ. of Wisconsin (715) 356-9494

R folks, I can't seem to find the instructions in the help files for the lattice package that explain how to add lines, such as with lines() or ?, to a levelplot. I'd be grateful if someone could point me in the proper direction. Cheers, Jeff ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Jeff Jorgensen Center for Limnology jcjorgensen at wisc.edu

...ite' and 'Treatment x Subsite' but without 'Site x Subsite'. I also want to analyse the "magnitude of effects" of all effects Is anybody out there who could help me with the function and the syntax Thanks and cheers!

Hi R-sters, Just wondering what I might be doing wrong. I'm trying to fit a multiple linear regression model, and being ever mindful about the possibilities of autocorrelation in the errors (it's a time series), the errors appear to follow an AR1 process (ar(ts(glsfit$residuals)) selected order 1). So, when I go back and try to do the simultaneous regression and error fit with gls,

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

Dear all, I'm calculating matrix correlations with permutation tests and I got this funny result. All correlation coefficients are the same with mantel.test {ncf} and pcol {simba} but the two functions yield dramatically different p-values (using the same number of permutations). Could anyone please enlighten me what is causing the difference and which result I can trust? (My matrices

I need to solve a system of non-linear fourth-order differential equations. Is there a command which solves this system? Thanks in advance.

Hello, I am working in R 2.13.2 GUI 1.42 Leopard build 32-bit (5910) on a MacBook Pro. I am working with a data frame of 22 columns and approximately 7,100 rows. I have been using the package scatter3d routinely to work similar data sets. However, when I tried to use scatter3d to work with this new data set I get the following message... Error in dyn.load(file, DLLpath = DLLpath, ...) : ? unable

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

For starters, let me say again how impressive R is, and how all of the effort that has gone into R shines through clearly. It is an amazing program, and I am frequently pleasantly surprised to find out how powerful and capable R is. Finding the interface to xgobi is the latest pleasant surprise. Are there functions in R for Major Axis and Reduced Major Axis regression? I have OBS-RESID graphs of

Hi, I have the same problem and, at a first look, the issues reported by the CRAN checks seemed easy to fix. However, after checking it again locally and on http://win-builder.r-project.org it appeared that GCC 4.9.3 (Windows, Rtools 3.4), same also on win-builder reports even more issues, especially legacy Fortran (mainly Roger's #2 and #3), but also "warning: ISO C forbids

Hi, I am almost new to R. Would any one show me (please include an example) how to clip a contour or image figure so that I only see the image or lines inside a selected area?

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 ...
