Hello, I'm creating a loop to work with vegan, to get a species abundance curve. Here I send the script I've created and also an excel file to prove what it can do. Well, I have a database with 20 years, and each year we have sampled 19 stratum, and in each estratum we have carry out some sumpling. Then, with the script that I've sent I've got to calculate the species abundance

Hi List, I’m using the vegan function specaccum to produce a rarefaction curve. In the function’s help it says: “Function ‘specaccum’ finds species accumulation curves or the number of species for a certain number of sampled sites or individuals”. Well, I would like to finds this curve for individuals, but when I compute it the function (using the ‘rarefaction’ method) gives me Sites, Richness

Dear List, today I turn to you with a next problem. I'm trying to compare species richness between various datasets (locations) using species accumulation curves (Chapter 4, page 54 in Tree diversity analysis<http://www.worldagroforestry.org/treesandmarkets/tree_diversity_analysis.asp>by Kindt & Coe). To accomplish this I'm using package BiodiversityR. My data is comprised of

Hello, I'm sure that this question is too simple, but, I'm begining with R and I'm not able to change the NA values in a matrix by 0 values, and it's necessary for my work, how can I do It?

Please I need some help using R to analyze my data. What I would like to do is to repeat the same basic process (e.g. linear regression between wood density and distance from pith) for at least 240 data subsets within the main data-frame. Within the main data-frame, these data subsets will be defined by three variables namely,  species, individual and core (i.e. 20 species, at least 6

Hi all: I get the following error message that I am not able to resolve. Error in if (const(t, min(1e-08, mean(t)/1e+06))) { : missing value where TRUE/FALSE needed It appears right before the last data.frame statement. Below is the program that simulates data from one way random effects model and then computes normality and bootstrap confidence interval for

Does anyone know of any programs capable of fine tuning my screen display settings? I'm using the NVIDIA drivers, and everything is slightly blurry - regardless of how much (or little) I set anti-aliasing to.

Hello, I have a question regarding bootstrap confidence intervals. Suppose we have a data set consisting of single measurements, and that the measurements are independent but the distribution is unknown. If we want a confidence interval for the population mean, when should a bootstrap confidence interval be preferred over the elementary t interval? I was hoping the answer would be

Hello, I have little experience with r, so I wonder if someone could help me? I need to plot a diversity measure (Fisher`s alpha) for different sites. I calculated the values using the following commands: Data(BCI) alphaBCI <- fisher.alpha(BCI) I need boxplots showing the data variation between sites. Then I tried: boxplot(as.data.frame(alphaBCI)) However, it does not appear the box plots

I won’t be able to attend, but I’d be interested in hearing if any conclusions are reached on several of these topics: > On 16 Oct 2015, at 21:27, Joe Ranieri via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > - Dealing with the explosion of basic blocks that come up with > languages where almost every function call, implicit and explicit, can > raise exceptions.

I updated my backup server this weekend from CentOS 7 to CentOS 8. OS disk is SSD, /dev/md0 are two 4TB WD mechanical drives. No hardware was changed. 1. wiped all drives 2. installed new copy of 8 on system SSD 3. re-created the 4TB mirror /dev/md0 with the same WD mechanical drives 4. created the largest single partition possible on /dev/md0 and formatted it ext4 5. waited several hours for the

Hi, I have a S4 based package package that was loading fine on R 2.5.0 on both OS X and Linux. I was checking the package against 2.5.1 and doing R CMD check does not give any warnings. So I next built the package and installed it. Though the package installed fine I noticed the following message: Loading required package: methods Error in loadNamespace(package, c(which.lib.loc, lib.loc),

Hi, I am trying to see if I can use R to perform more rigorous regression analysis. I wonder if the fingerprint package is able to handle pipeline pilot fingerprints (ECFC6 etc) now. Thank you, Eric [[alternative HTML version deleted]]

Hi Alli need some information about how i can extend the HDD in domU. I am a domU having 10GB of disk assigned to it now which is running out of space. is there a way i can assign a other 10GB space to the system in such a way that it appears as a single HDD of 20GB without loss of data.

dear R-friends, i`ve got a large dataset of vegetation-samples with about 500 variables(=species) in the following format: 1 spec1 1 spec23 1 spec54 1 spec63 2 spec1 2 spec2 2 spec253 2 spec300 2 spec423 3 spec20 3 spec88 3 spec121 3 spec200 3 spec450 . . this means: sample 1 (grassland) with the species (=spec) 1, 23, 54, 63 is it possible to get a following data-structure for further
