Neil is my new bioinformatics hero! (Sorry Pierre :)BioStar is a Q&A website for bioinformatics, just like the Blue Obelisk eXchange. Neil and Pierre have an ongoing struggle to gain the most karma, requiring Pierre to put in a formal complaint aga...

Harvesting user IP addresses BioStar user profiles (here’s mine) include a location field. It’s free text and optional, which means that location is missing or inaccurate for many users. However, if you’re logged into BioStar 
Those who follow the discussions about UHI understand that “nightlights” plays a large role in defining whether or not a station is considered Rural or Urban. In the work of GISS nightlights are determined by looking at the DSMP product. The product is available in 30 arcsecond format. That’s .00833 degrees. The following issue arises. 
Hmm, lets see how a fusion table works with map maker. The process works like this. We read in the GHCN inventory file into R. ( see code below ) We then clean it up ( the names fields and missing values) and we output it to a *csv file. Then open the csv in 
Just a short update on ICOADS. I started out an ICOADS project with grand plan to reprocess the observation files into a “raster” format. That ends up being a really big job. Along the way I had to learn a new package Rcurl and relearn some old Unix skills for compiling RCurl. Along the way 
Having done the plot with python+matplotlib, thought I would have a go reproducing it in R, using only the builtin "plot". So, just to recap - this is a plot of the sun times (rise/set,twilight and blinding) as generated by the great python library pyephem. The R code reads in a csv file as output from a...
Here is how to improve your charts, graphs, maps, and plots: Erase non-data ink. Erase redundant data ink. Maximize the ratio of data to ink. Show data variation, not design variation. The surface area of graphical elements should be directly proportio...
A few hours ago, Jens Oehlschlägel has announced on the R-help mailing list of the release of a new version of the ff package. The ff package provides data structures that are stored on disk but behave (almost) as if they were in RAM by transparently mapping only a section (pagesize) in main memory – the effective virtual memory...
There are various ways to plot data that is represented by a time series in R. The ggplot2 package has scales that can handle dates reasonably easily. Fast Tube by Casper As an example consider a data set on the number of views of the you tube channel ramstatvid. A short snippet of the data is shown
Time for another dump of the entire package. Get the zip file 5.1 in the box to the right. ( shortly). unzip and run the following files if you havent already: 1. downloadall.R 2. setup.R If you are running for the first time, You’ll note I added diagnostics. Sometimes the files get corrupted on download
