rkward on Ubuntu heron with R2.8.0
I am running R on Ubuntu Heron. I recently updated to R 2.8.0 from the default (2.6) in the Ubuntu heron repository by adding deb http://cran.stat.sfu.ca/bin/linux/ubuntu hardy/ I updated all packages installed in /usr/lib/R/site-library and those in my home directory /home/duncan/R/i486-pc-linux-gnu-library/2.6 without obvious issues. I installed adehabitat and gpclib, which should be good

How to draw holes generated by gpclib using plot function
Hi. I've tried to create a polygon with one hole by gpclib using following example script. holepoly <- read.polyfile(system.file("poly-ex/hole-poly.txt", package ="gpclib"), nohole = FALSE) area.poly(holepoly) plot(holepoly,poly.args=list(col="red",border="blue")) And I noticed plot function couldn't draw polygons with holes correctly.

GIS re-mapping / polygon overlap
In Germany the Unemployment Agency uses a sectioning of the german map that is different from the usual Administrative Boundaries. Some demographic data are available in Administrative Boundaries only, some in Unemployment Boundaries only. I would like to generate estimates in one boundary system of data availabe in the other boundary system, and would appreciate advice concerning the following

tapply and NA value
Hi, I'm writing for a little help. I have a dataframe with same NA value and I'd like to obtain the means of the value of a coloumn grouped by the levels of a factor coloumn of the datframe. I'm using the function "tapply" but I see that if only a NA value is present the result is NA. There is an option to have the correct result or I must use an other function? Thanks of

How can I use Adehabitat to obtain an .asc object with the predicted values of a niche model?
Dear all, I'm using the package adehabitat in R to import several .asc files (=matrix), and also create a kasc object (=dataframe) with all of them. The main idea is to use this kasc object to map the predicted values of climate-matching model for an overall area. However, I don't know how to proceed: Do I have to project the model (already stored in R) onto the kasc object directly, or

lda discriminant functions
Hi list, I'm looking about lda function. I'd like to know how calcolate the value of the discriminant functions for the original datas. I see that in the result object "lda" there is $scaling a matrix which transforms observations to discriminant functions, normalized so that within groups covariance matrix is spherical. I'd like to have the value of the discriminant

bar charts
Hi, I'd like plot a bar graphic of a array. I'd like to have the values of the single columns as juxtaposed bars (like in "barplot" with beside=TRUE) and I'd like to have the values of the single columns expressed like percentage of the sum of the coloumn. In this way all the bars are composed by the sum of the percentage of the values of a coloumn (with different colors)

New package: gpclib
I have just uploaded a package to CRAN called `gpclib' for clipping large and complex polygons. This package provides an R interface to Alan Murta's very fast General Polygon Clipper library (written in C), which has an optimized version of the Vatti algorithm. Not all features of Murta's library are implemented -- right now you can do intersections, differences, and unions. There

adehabitat version 1.2
Dear all, I have just uploaded to CRAN the version 1.2 of the package 'adehabitat'. This package now contains new functions for the estimation of home ranges (Nearest neighbour convex hull, brownian bridge approach for kernel estimation), estimation of schoener's ratio. This package now allows a better management of objects of class "area" (see plot.area, perarea, ararea).

Calculating home ranges using mcp in adehabitat
Hello, I've been trying to calculate home range sizes (for Icelandic geese!) using minimum convex polygons with the adehabitat package. I've tried to use the R code shown by demo(homerange) in adehabitat and when that didn't work I've fiddled around with it but to no avail...Below is the output of the demo that I've attempted to follow, followed by a subset of my data (for one
