similar to: null model for a single species?

Dear R helpers, I have a data set with 4 types (W, C, E & S). Now I have values for all types plus all possible combinations (the order is unimportant): W, C, WC, E, WE, CE, WCE, S, WS, CS, WCS, ES, WES, CES & WCES. Ideally I would like to represent everything in one graph and as concise as possible. Drawing 4 circles and depicting it as overlap just gives me 13 out of the 15

Dear R-helpers, I would like to export hierarchical clusters e.g. fit <- hclust(d, method="ward") in the newick format write(hc2Newick(fit),file='hclust.newick') Searching for a possibility I found this solution in the package ctc (http://www.bioconductor.org/packages/bioc/html/ctc.html). However, neither from this site nor via CRAN it is possible to install the package.

Hello, I have some measurements that I am trying to fit a model to. I also have uncertainties for these measurements. Some of the measurements are not well detected, so I'd like to use a limit instead of the actual measurement. (I am always dealing with upper limits, i.e. left censored data.) I have successfully run survreg using the combination of well detected measurements and limits,

hello, is there a way to control figure margins using package lattice, similarly to parameters mai/mar (which presumbly works only for figures of package graphics)? thanks!‎ [[alternative HTML version deleted]]

Hi to All, I am building a package in R and whenever I run command "R CMD build OAR" in the terminal, I get the following error: * checking for file ?OAR/DESCRIPTION? ... OK * preparing ?OAR?: * checking DESCRIPTION meta-information ... ERROR Malformed Depends or Suggests or Imports or Enhances field. Offending entries: R (>=3.0.2) Entries must be names of packages optionally

Hello! I have a fallback mount point with <fallback-override>. When my source client reconnects, the media player is moved mack to the right mount point but the media players I have tried (mplayer and VLC) keep playing the fallback. Is this because of my source client (liquidsoap), icecast or the media players? I think I noticed some message in mplayer about mime type or something.

[AMD Official Use Only - Internal Distribution Only] Hi All, For the AMDGPU architecture, during RA, we prefer to have a cost associated with the registers (CostPerUse) based on a target entity (for instance, the Calling Convention of the current MachineFunction). Presently CostPerUse is a one-time static value (either zero or a positive value) generated through table-gen. The current

Hello! Icecast behaves oddly for me in debian testing, somehow the permissions on my log file directory was set to root:adm if I remember things right. Also there was no systemd service starting when I tried to start from /etc/init.d, somehow init services refer to systemd services nowadays whether they exist or not. I tried to create a systemd service looking like this: [Unit]

I dont know the history behind CostPerUse word so I may be missing the background associated with it. It seems that it's misnomer for what it is intended. At first sight, the word indicates that the cost is a function of uses of the register - more the uses more the cost. How do we want to define the value of CostPerUse. Should it be a function of uses? or just the target? On Sat, May 30,

Hello, I have to run a general linear mixed model which looks at 2 dependent variables at the same time (var1 divided by var2). I have tryed to search for such a kind of model structure but since I just started using R my search was not successful. Especielly since I only have an old SAS GENMOD code structure from my project supervisor as an indication. My question is no, does there exist a code

Hello, I''ve setuped an ethernet bridge on a debian sarge 3.1 with l7-filter + ipp2 shapper rules The server is a supermicro p4sci + celeron pentium 4 base 3ghz + 512Mb + 2 ethernet e1000 One interface is connected to a cisco catalyst switch The other interface is connected directly to a CMTS (a sort of router for cable modem) configured as bridge too. More than 20Mbps of bandwith

Hi to all, Is there a way we can fit a non linear model to a data using non linear least square method without necessarily initialising the parameters of the model. I find it hard to get the initial value of the parameter. Below is a sample of the code I have. *nachman<-nls(OARmedium$OCCUPANCY~1exp(-alpha*OARmedium$MEAN^beta),start=list(alpha=0.2,beta=0.1),data=OARmedium)summary(nachman)*

I attempted to contact Drew Tyre, but the email I have for him is no longer in service. Hopefully someone can help. I'm using obs.error in R to model turtle occupancy in wetlands. I have 4 species and 20 possible patch and landscape variables, which I've been testing in smaller groups. > zib.out<-obs.error(y=painted,m=numvis,bp=zvars,pcovar=7) I get the following error

Hi to All, I am fitting some models to a data using non linear least square, and whenever i run the command, parameters value have good convergence but I get the error in red as shown below. Kindly how can I fix this problem. Convergence of parameter values 0.2390121 : 0.1952981 0.9999975 1.0000000 0.03716107 : 0.1553976 0.9999910 1.0000000 0.009478433 : 0.2011017 0.9999798 1.0000000

Dear Tomas, Thanks for your commitment to fix this issue and also to add the chunk size as an argument. If you want our input, let us know ;) Best Regards On 02/26/2018 04:01 PM, Tomas Kalibera wrote: > Dear Christian and Henrik, > > thank you for spotting the problem and suggestions for a fix. We'll probably add a chunk.size argument to parLapplyLB and parLapply to follow OpenMP

Hi everyone, I am working with the dbFD function of the FD package, and there's something funny happening with the value of sing.sp in the output. Basically, I have a species-function matrix and a community matrix. One site in particular has 6 species, 4 of which have identical functional coding. I thus expect nbsp = 6 and sing.sp = 2 for this site. However, nbsp = sing.sp = 6. This

Dear all, I am new to R and even newer to mapping with R. I have installed PBSMapping, maptools and maps, and I am struggling to produce a map of fish abundance in the Grand Banks. I have tried several approaches to plot the bathymetry in my study area: 1) download the data from http://topex.ucsd.edu/cgi-bin/get_data.cgi (42N46N313W307W) To start with, the map I get is blank between

Dear List, I am running constrained correspondence analysis for abundance data of 7 birds. However, I would like to check which bird prefers which environment gradient by showing the species with different colors of the dots in cca plot (package vegan). Please kindly help and thank you Elaine [[alternative HTML version deleted]]

Dear all, I'm performing a detrended correspondence analysis on vascular plant community data (296 species), and I have a question on the species scores projected in the ordination diagram. When I run a ordiplot all species are projected in the output graph, but I'd like to restrict the number of species plotted in the final graph. Some species are so rare in the data, that no relevant
