Hi! Im new to R and I need to interpolate a shapefile using kriging. I've been able to plot/read the shapefile using the package maptools or rgdal. I've searched the internet for sample codes but most of the kriging codes that I've found done in R is done using txtfiles or CSVs.  An example could be of great help. Thanks.

Hi, I'm playing with moving some of my lattice graphics into ggplot2, and I'd like to ask how to achieve a couple of things, both of which are fully illustrated in self-contained code (and mostly minimal, although that left quite a bit) following this written description. 1. I quite often like to use a 'ghosted' reference across facets - for example, in my example program below,

Hi, The following command: axis(1, at= 1:50, labels= sampleNames(data)) produces an X-axis with 50 ticks and labels drawn from the sampleNames namespace. Problem is the labels at each tick are printed parallel to the x-axis and thus run into each other. How do I specify for the labels to be printed perpendicular to the x-axis? Thanks in advance.

Hi!! I'm looking for a package in R for time series analysis using wavelets( I'm interested on extractingt information from electrocardiograms with the aim of study the heart rate variability) so i want to know which package is the best for me. I've thinking about using some of those(you can recommend me others,xD): *wavelets: A package of funtions for computing wavelet filters,

Dear R-help members, To whom it may concern, our research group is conducting a study to evaluate the predictive value of 24 hour blood pressure variability. We are looking for an R routine that performs a fast Fourier transform spectral analysis (with an output of the approximation function of the Fourier and estimates the validity of the model for the various harmonics). Thanks Vittorio

Dear list, I'm trying to download a text file directly from the internet using the RCurl package and the command getURL.

Hey, I have code that can check the quality of a data set we're working with (expression data), and I'm having some trouble writing code that would make the expression data we have tie to other data we want to link it to (called phenotype data). Does anyone have any advice on how I could make a single object that would do this? Other relevant info: I want to use the pdata() function,

Dear All I would need to generate differences between variates such as nam1<-nam2-nam3 in the following loop: for(i in c("13","26","38")) { for (j in c("HR","PQ","QRS","QT")){ nam1<-paste("d",j,i,sep="") nam2<-paste(j,i,sep=".")

Hi, I'm very confused about R structures and the methods to go with them. I'm using R for microarray analysis with Bioconductors. Suppose without reading the documentations, what's the best way to explore a data structure when you know nothing about it? I am currently using is() / class() to see what the object is. str() / attributes() to probe inside the object, and

hey, i am using the flickr wrapper for ruby and need to access the tags of a specific photo. i got all the rest working. i must admit i am kind of new to ruby, but i tried and tried and couldn''t figure it out. among other things i want to read geotags like in my example here: http://www.flickr.com/photos/whoisstan/146634506/ i''m sure it is deadsimple and i just overlooked it.
