three-dimensional (volumetric) estimation from x,y,z points
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 donĀ“t know how to estimate the volumetric
space.
Any help are welcome.

Re : three-dimensional (volumetric) estimation from x,y,z
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.

netCDF to GeoTIFF by layer in r

We can't tell what is in the ncdf file from what you report other than it has 4 bands (layers) and that the first is called 'Volumetric.water.content.at..33.kPa' If you want to know more about the what is in the file, then I suggest you use the ncdf4 package to open the file and explore it's contents - you should get a clear picture of it's contents from that. Something like this (untested)...

Fwd: netCDF to GeoTIFF by layer in r
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"

nuisance variables
*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 i...

Using the R predict function to forecast a model fit with auto.arima function
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:

Postfix on one host/Dovecot (mailboxes) on another - How?
...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

Vis5D interface package
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 com...

finding an unknown distribution
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

Workarounds for Splinter Cell: Conviction
...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 workar...

Monty on holiday
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
