similar to: nMDS with R: missing values

The R-exts manual says about 'Suggests' field in package DESCRIPTION: "The optional `Suggests' field uses the same syntax as `Depends' and lists packages that are not necessarily needed." However, this seems to be a suggestion you cannot refuse. If you suggest packages: (a line from DESCRIPTION): Suggests: MASS, ellipse, rgl, mgcv, akima, lattice This is what happens:

Hello, I can draw a basic stress plot for NMDS with the following code in package Vegan. > stressplot(parth.mds, parth.dis) When I try to specify the line and point types, it gives me error message. > stressplot(parth.mds, parth.dis, pch=1, p.col="gray", lwd=2, l.col="red") Error in plot.xy(xy, type, ...) : invalid plot type In the above code, if I removed line type,

I'm not sure how you are incorporating time period into your data structure. Typically we are looking at plots or assemblages as the rows and taxa as the columns. Time period adds a third dimension that could be added as blocks of rows. For example, depending on the resolution of your data, one approach would be to have up to 8 rows for each locality: Loc1.1000, Loc1.2000, . . . Loc1.8000. If

Dear R-community, dear Jari Oksanen! I use metaMDS (package vegan) to calculate NMDS. In a lot of papers I read that it is recommended to use previous best solutions as a new starting configuration to get better results and to avoid local minima. On the help page I found that a previous.best-command is already implemented in metaMDS: metaMDS(comm, distance = "bray", ...,plot = FALSE,

Dear Mr Moderator, please let me through. I want to reply to my own thread. I once subscribed to this list, but then my subscription was not accepted. Now to the business: The final failure came from missing .install.macbinary() function. I grepped R-patched sourcesand the only instance of .install.macbinary() was the call to the function in R- patched/src/library/utils/R/packages2.R (stupid

Hi! Thanks for providing great help in R-related statistics. Now, however I'm stuck. I'm not a statistics person but I was recommended to use R to perform a nmds plot and PerMANOVA of my dataset. Sample(treatment) in the columns and species (OTU) in the rows. I have 4 treatments (Ambient Temperature, Ambient temperature+Low pH, High temperature, High temperature+low pH), and I have 16

Canberra distance is defined in function `dist' (standard library `mva') as sum(|x_i - y_i| / |x_i + y_i|) Obviously this is undefined for cases where both x_i and y_i are zeros. Since double zeros are common in many data sets, this is a nuisance. In our field (from which the distance is coming), it is customary to remove double zeros: contribution to distance is zero when both x_i

Dear r-Community, Step1: I would like to calculate a NMDS (package vegan, function metaMDS) with species data. Step2: Then I want to plot environmental variables over it, using function envfit. The Problem: One of these environmental variables is cos(EXPOSURE). But for flat releves there is no exposure. The value is missing and I can't call it 0 as 0 stands for east and west. Therefore I

I find it a bit peculiar that a package skeleton created with a utils function package.skeleton() fails subsequent R CMD check. I do understand that the function is intended to produce only a skeleton that should be edited by the package author. I think that it would be justified to say that the skeleton *should* fail the test. However, I have two arguments against intentional failure: * When you

Message 2 of today: it works now. After re-installing R.app from the same R-2.1.0.dmg file, and fixInNamespace'ing(*) install.packages(), I managed to update 23 outdated packages from CRAN binaries for MacOS X. What I did was to: 1. change call to .install.macbinaries() into call to install.binaries() in install.packages(). install.binaries() is a function defined utils/R/aqua/GUI.R. 2. I

Thanks for the attention paid to my rpoblem. Please find enclosed the matrix with my dissimilarities. This is the only case in which sammon(), from the MASS package, gives me this kind of problems.

Dear R folks, One of the fantastic new tools in R is `Sweave'. I have tested it so much that I know it works and produces fine documentation, and with (GNU) Emacs/ESS it is nice to work with, too. I started to have a look at including some Swoven (is that a strong verb?) documentation with my R package, but it seems that there is no model to copy among those packages that I have installed in

Dr. Stevens, Hi, my name is Trey Scott, and I'm a grad student of Brian McCarthy's. He referred me to you because of your expertise in handling complex R problems. We were hoping you could help us solve a nagging problem that is prohibiting me from producing graphicl output. Here is a simple mock-up of the matrix I'm using a b c d e f 1i 1 4

Hi, I've been using R for a while now but I've got a problem with metaMDS (in the vegan package) that I can't quite figure out. I have a set of proportion data (from 0-1, rows sum to 1) that I apply metaMDS to using the command: nMDS.set=metaMDS(sqrt(test.set),distance="euclidean",k=3,zerodist="add",autotransform=FALSE) I am using a squared-chord distance
