similar to: FD: R package to measure functional diversity indices

Dear all, I have a question about FD package. I?m trying to calculate functional diversity indices using insect data. My trait data includes dispersal ability (0, 0.5, 1), body size (continuous) and five feeding guilds coded as in percentages (for example; 0,0,0.5,0.5,0) since some of the species can have two different feeding guilds. However, the package only calculates when I run ?calc.Frich=

Function/file names are hypothetical. Say I have written myfunction.R, which calls myfunction.c via .C("myfunction", ...). I've compiled successfully myfunction.c via R CMD SHLIB myfunction.c in the terminal. Then, in the R console: dyn.load("myfunction.so") source("myfunction.R") test <- myfunction() # works fine So everything is in order, myfunction works

Sorry if this has been answered somewhere else (didn't see it), but is cran2deb fully compatible with Ubuntu? Novice question: I use install.packages() within R. The pros of using sudo apt-get instead seem obvious, but are there any cons I should know about?

Hello I'm currently using the dbFD function of the FD package and i'm having some things that I can't do. Is there any way to check the relations between dbFD indexes? Function cor for example? I can't manage to put the informations correctly dbFD function gives a lot of output (indexes - nbsp, sing.sp, FRic, FEve, FDiv, FDis and RaoQ). I want to see the relationships between

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

After upgrading to R 2.10 and upgrading and testing JGR 1.7, I and other Ubuntu users are getting repeated error messages in JGR that look like this: > Error: could not find function ".getModels" Error: could not find function ".getDataObjects" Error: could not find function ".getOtherObjects" Error: could not find function ".getFunctionsInWS" The

Is it possible to encode/decode more than 2 channels (stereo) stream with Speex ? We are currently recording one,two or four channels stream and we had to customize an ADPCM codec for the four channels part. ------------------------ Stéphane Laliberté Analyste-Programmeur Novo Technologie inc. <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

Dear List, I can'f figure how to add point labels in the next plot (example from ?taxondive help page, from vegan package): library(vegan) data(dune) data(dune.taxon) taxdis <- taxa2dist(dune.taxon, varstep=TRUE) mod <- taxondive(dune, taxdis) plot(mod) The points in this plot are diversity values of single sites, and I'd like to add a label to each one. The plot command don't

Hi everyone, I would like to share a paper my co-authors and I published at CGO 2013, where we used profiling support in LLVM for efficient code layout randomization: Andrei Homescu, Steven Neisius, Per Larsen, Stefan Brunthaler, Michael Franz.

The attacker is forced to rely on side channel information such as timing channels in an attempt to discover the length of the inserted NOP sleds. This sounds like an extraordinarily difficult task, but possibly doable. With a

Hi   I want to make a grid map using diversity indices. I have a soil grid map with 7 class in r. how can I make a diversity map based on soil map in r?  I found something for calculation diversity in a table (.csv).   Thanks [[alternative HTML version deleted]]

Dear R-help members. Maybe this is not the right platform to ask this, but I'm looking desperately for a test which is calculating confidence intervals from diversity measurements (non-normaly distributed) (fishers alpha diversity). I was checking the package "vegan" but there seems to be nothing useful. Does anyone of you know with what package I easily could calculate such a

Hi, I have a small simple data frame (attached) - to compare diversity of insects encountered in disturbed and unditurbed site. What i have is the count of insects - the total number of times they were encountered over 30 monitoring slots. Can someone please check for me to make sure how the 'community data matrix' for the diversity function needs to be oriented so that i'm

Hi All, It's my pleasure to announce the Diversity and Inclusion in Compilers and Tools workshop that will be held on the afternoon of April 5th, at the same venue as the EuroLLVM'20. This event features speakers and discussion aiming to increase diversity and inclusion within the LLVM community, attendee's workplace or university, and within the field of compilers and tools. It is

I read a lot of white papers, but is there not any open source implementation of SFI or artificial diversity? I google around, but I can't find anywhere anything regarding what I could openly download. In the same respect, I would also like to make an innovation proposal to create such an endeavor if there is not one already. -------------- next part -------------- An HTML attachment was
