similar to: calculation of diversity confidence interval

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

Hello I'm trying to calculate 2d confindence bounds into a scatterplot using the function "kde2d" (package MASS) and a contour plot. I found a similar post providing a solution - unfortunatly I do not realy understand which data I have to use to calculated the named "quantile": Post URL: http://tolstoy.newcastle.edu.au/R/help/03b/5384.html > (...) > >> Is

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

Dear all, I'm using R2.8 version, and am trying to do NMDS and calculate other diversity indices in vegan package. The problem is that it works with a small set of data (43 X 23; row by column), but the following error message comes up with a larger data set (43 X 104) (it seems not large to me at all). I made it sure that all data are of numeric type as required. >gh1.H=diversity(gh1)

Hi, May I know how to obtain the confidence interval of the survival curve of weighted Cox regression model? I tried coxph, cph, and coxphw, but they did not work. Any help would be much appreciated.

Dear R users, I know, the topic is more related to the r-sig-ecology. I decided to post it to the r-help as some specific topics of my question deals with NA-values and RDA (R vegan) and an adaptated RDA code due to a specific study design (including a second matrix). I am calculating a RDA for a dependent matrix (different variables for tree performance) and different explanatory

Dear Colleagues, As a novice I was trying to calculate Shannon diversity index using diversity function in vegan package and kept having same error message. Error in sum(..., na.rm = na.rm) : invalid 'mode' of argument My dataset is from microarray and have abundant missing values, so I tried labeling them as NA and 0, but still same error message. Shannon index is negative

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 Friends, Using package Vegan, I need to calculate Shannons Diversity index and Pielou's Evenness for a set of 20 study areas. Each area is represented by a matrix of 25 sample plots x tree species. The code is as following, where data stands for the data matrix of any of the 20 areas: S <- specnumber(data) H <- diversity(data) J <- H/log(S) I indexed the 20 areas by a

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

Dear List, I have been experimenting with building packages from sources, having previously relied upon the binaries. I downloaded and installed all the tools suggested in http://www.stats.ox.ac.uk/pub/Rtools/ , including ActivePerl 5.6.1.631. I also downloaded the HTML Help workshop exe and installed it. During install though, a message popped up to say that I had a newer version of the

Thanks for all the feedback! It seems there is some interest, so I thought I'd try to summarize discussions so far, and provide patches for closer inspection. I'm not sure if patches should end up here or on a different list in this instance, so if I should instead send this to a different list, I'm happy to do so. - Is diversity needed, or are existing protections sufficient? As

Hi, forgive me if someone has already posted about this but I have had a look and cannot find the answer, also I am very new to R and been getting the grips with this. I have been trying to use Adonis to find out if there are significant difference between groups on data that I have analyses with NMDS, and have been struggling with getting this to work and understanding what is going on. I am

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
