Dear all, I have a set of x,y,z points obtained from a lizard species and now I would like to estimate the three-dimensional use of space for this species. I know that 2D area I can estimate using adehabitat packages, but I don´t know how to estimate the volumetric space. Any help are welcome. Miltinho Brazil [[alternative HTML version deleted]]

You may use the "geometry" package and the "convhulln" function. This will allow you to compute the convex hull volume of a set of points in a n-dimensional space. -- Guilhaumon Fran?ois Laboratoire "Ecosyst?mes Lagunaires" UMR 5119 cc 93 Bat 24 Universit?

Something like this (untested)... library(ncdf4) x <-...

Hi I have a netCDF file of volumetric soil water content at four different soil layers and want to convert each soil layer in the netCDF file to a GeoTIFF layer. This code converts the netCDF file to one GeoTIFF layer, i.e. unclear which soil depth. file.nc <- "C:/Soil_Weather_data/Agro/VMC21/VMC21.nc" file.tiff <-...

*Dear experts,* Please excuse me for disturbing... Right now I am struggling with GLM a bit... Would you be so kind to provide me a solution on using nuisance variables. The problem is that I have data on Depression (volumetric measurements of different brain regions) and I want to include age, gender and education as nuisance parameters in the model. In the other words I would like to model the model depression scores in respect to volumes, considering the mentioned variables as nuisance ones. Could you please tell me...

Hello R users, Hope everyone is doing great. I have a dataset that is in .csv format and consists of two columns: one named Period (which contains dates in the format yyyy_mm) and goes from 1995_10 to 2007_09 and the second column named pcumsdry which is a volumetric measure and has been formatted as numeric without any commas or decimals. I imported the dataset as pauldataset and made use of the auto.arima function which is great when you want R to suggest an appropriate arima model to fit to your data. I successfully got the arima fit by coding: > pau...

...second machine, where the imap server sits). second machine: just dovecot and user's mailboxes. (I need to keep this machine doing only this task, because of the load) Is there a way to do that just by adding a mailbox_transport to the first machine's postfix? thanks = Mobile (Volumetric) Concrete Mixers The innovative leader in the mobile concrete mixer industry.

Greetings, Summary: Has anyone else started a package (or have code) with the capability to write Vis5D-readable netCDF files containing irregularly-spaced data? I've recently put together what might be the beginnings of a (GPL'ed) R interface package to the Vis5D volumetric visualization program (http://vis5d.sourceforge.net). Vis5D is commonly used in the atmospheric science and computational fluid dynamics fields. But it is generally useful for visualizing (e.g., animating) any function across 3D space and time, i.e., F(x,y,z,t). [It's also GPL'ed and c...

Hi, I need to analyze the influences of several factors on a variable that is a measure of fecundity, consisting of 73 observations ranging from 0 to 5. The variable is continuous and highly positive skewed, none of the typical transformations was able to normalize the data. Thus, I was thinking in analyzing these data using a generalized linear model where I can specify a distribution other than

...th any other version.) 6. run regedit and set the following Direct3D settings: "AlwaysOffScreen" "enabled" "StrictDrawOrdering" "enabled" The game runs fine without these, but some gfx glitches occur when these settings are not enabled, most notable is the volumetric fog toggling on/off randomly as well as light reflected off glass seems to be buggy too. 7. run the game. The game is pretty resource demanding, so I'm playing on low quality settings. With all this done, I'm able to play for hours with very smooth gameplay. Let us know if these work...

Hi folks, My wife and I are taking a long weekend to celibrate our anniversary. I won't be around again until Wednesday to answer email or do anything else on Vorbis. Yeah, I know, I usually answer my email once a month anyway (so likely no one would notice me being gone), but just so folks know if anything really juicy comes up :-) I'll be merging my latest branch with mainline
