Dear colleagues, There are still a limited number of seats available for the* International Summer School* organized by Spatial Ecology (www.spatial-ecology.net) <http://www.spatial-ecology.net/> held at the Univ. of Basilicata, in the magnificent town Matera...

That?s the right way to motivate me. Will let you know about the results. Last thing, because of the unkind comment can you help me solving one thing but radiant? I downloaded the packages thank opened it but in...

Guys, I posted this on R-help and Dirk kindly pointed out that this list is a much better place for this sort of questions... I was wondering whether anyone experimented with Rcpp and static variables. I remember reading that...

I have the following problem. After having created an xts importing data from a csv with: data <- read.csv(mib.csv, header = TRUE, dec = ".", sep="\t") dates <- as.POSIXct(strptime(data[,1],format="%m/%d/%Y")) mib <- xts(data[,c...

Hi, first of all happy new year! I'm trying to do forest species distribution at European level (1 km resolution) by means of randomForest running it in a cluster computer. I'm using several predictors of different data sources...

Dear Colleagues, For the first time Spatial Ecology is organizing a course in Spanish. *Geocomputaci?n para aplicaciones ambientales: uso de GDAL y GRASS* ( https://spatial-ecology.net/curso-geocomputacion-para-aplicaciones-ambientales-uso-de-gdal-y-grass-2024/ ) "Objetivos...

Dear colleagues, With the objective of enhancing programming skills in Geocomputation and prepare new scientists in deals with large geo-data, in August 2018 we organize a summer school at Berkeley. *International Summer School:* *Geocomputation using free and Open Source...

I often use Lyx/Sweave and I typically write in english. Today I had to write a document in Italian and, as many of you know, many italian popular words use ?, ?, ?. ?, etc. I discovered that if I type in Italian...

Brian, I have a patched version of the function, I attach it at the end of this mail. I'm having problems with the SharpeRatio function as well. >SharpeRatio(managers[,1,drop=FALSE], FUN="StdDev") HAM1 StdDev Sharpe: (Rf=0...

Ciao Maurizio - Try to build up your table outside R and enter in R just with the columns/rows that you need. - If you are fitting the model use y=resp , x=prdictors rather others formulas (e.g.: y ~ ) - Every...

Dennis, Yes, Reduce works, but unfortunately it does not speed up the evaluation time (actually, it makes it a little bit slower). Thank you anyway. On Tue, Mar 29, 2011 at 2:21 AM, Dennis Murphy <djmuser at gmail.com...
