No...but it works! I do not know why I did not find it... Many thanks! Hi David, thanks to you as well. Greg Snow schrieb: > Did you try gray.colors(3)? >
Hi Pierre, I think intersect.nb in the spdep package is what you are looking for? Have a look at the example there, looks quite similar to your problem. HTH, Jens -- +++++++++++++++++++++++++++++++++++++++++ Dipl.Biol. Jens Oldeland Biodiversity of Plants Biocentre Klein...
Dear R-Users, I was wondering if there is a way to test the significance of the clarkevans statistic in spatstat package? I did not find any related function or the related values to calculate it by hand. does someone...
Dear Mixed-Model SIG I am trying to use serial and spatial correlation structures in a gamm model. g2 <- gamm(sqrt(pp10M.day) ~ s(tempsurf, bs="cr"), data=data, random= list(Station= ~1), correlation=corARMA(form = ~ 1|Station, p =2...
Dear group, I am looking for a method that allows me to creating non-overlapping polygons from centroids with a known size. I have information on the location of farms in Azerbaijan. All farms have a specific size, but I...
I was recently told that it is not allowed to include static covariates in mixed effect models. There should be something written in "Applied Longitudinal Analysis, Fitzmaurice, Laird and Ware, Wiley & Sons, 2004. Chapter 12", however I do not have...
Dear Group, I am currently preparing a lecture on 'Cluster Analysis' and I found two very different ways to interpret a dendrogram. The first option is to 'cut' a dendrogram at a specific height, like it is possible with the...
Hi, I am working with two shapefiles in R; one is a point.shp the other is a polygon.shp. Now, I would like to intersect/join/attach all the values from the polygon to the table of the point...
Hi, I am facing a problem with the legend, I don?t know how to use the fill option in the legend in order to achieve the same standard gray levels that are plotted. Sorry for this easy one, but...
Dear R-sig-ecology group, is there a way to use two self-made dissimilarity matrices for the left-hand side (LHS) and right hand side (RHS) in vegan functions such as capscale or adonis? I created those matrices in...
Dear R-Users I have successfully imported my Shapefile using maptools with the following command lines, and I hoped that my object (nc) will be recognized as projected data, so I have included the CRS command: library(maptools) p4s = CRS...
Hi, I am looking for a way to add labels, i.e. absolute values, into a stacked bar chart using the basic plot functions of R. The labels should be inside the stacked bars. For example, ### I have this dataset...
Dear All, a short and maybe simple question: I have to rank all values in a matrix from 0 to X, [1] [2] [3] [4] [1] 0.1 2 0 3 [2] 50 3 3 1 [3] 100 1 1...
Hi, I know there have been some discussions on that topic. all their solutions failed in my case... My problem is that I have a dataframe with many zeros. but while plotting they are not useful. so I want to...
> How can I read and plot an ArcGIS raster file into R ? Hi Juliane, I think what you are looking for is something like a function in the "adehabitat" package called "import.asc". First you need to convert your raster...
Dear all, I have a problem with constructing a nested loop. I have two matrices: pnr: 800 rows 14 columns where rows are 40x20 meaning that 40 rows belong to one of twenty objects in the matrix pnr mvp: 20...
Dear group, I have used the as.mlm.cca(vegan) function to derive statistical measures for the goodness of fit of my environmental variables and the ordination axes of an RDA. I prepared a manuscript in which I used spectral...
Hi, sorry for beeing unprecise. I am looking for a legend that has the same colors as the barplot. For a coloured version I would simply use the same fill=rainbow() option as used in creating the barplot. However, this...
Dear list members, I have a question again on adonis and whether the interpretation is correct. I must admit that I am a big fan of ANOSIM, I think it is pretty simple to explain, in contrast to adonis. I...
