data.table, lattice, R, spatial data

Some days ago James Cheshire published the post Mapping Flows in R. I have implemented an alternative (faster) version using data.table to read and join the datasets (and lattice to display the results). If you are new to data.table you should read this wiki and this cheatsheet.

This is the code:

This is the result:

Etiquetas

forecast, meteorological data, NWP, R, WRF

Some months ago I published the meteoForecast package, with functions to download data from the Meteogalicia and OpenMeteo NWP-WRF services. Now there is a new version available at CRAN. This update includes a bunch of bug fixes, some additional features, and three new services: GFS, NAM, and RAP.

You will find detailed information and examples here.

meteoForecast, a package to obtain NWP-WRF forecasts in R

wrfDaysThe Weather Research and Forecasting (WRF) Model is a numerical weather prediction (NWP) system. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software for this.

meteoForecast is a new R package that implements functions to download data from the Meteogalicia and OpenMeteo NWP-WRF services using the NetCDF Subset Service.

Read this introduction for additional information and examples.

Agustin Lobo has recently published some good tutorials about rasterVis:

  • Introduction to rasterVis
  • Overlay your raster layer on a backround GoogleMaps layer
  • Overlay vectors on raster layers
  • Vectorplot

rastervisBTC

Regarding the second tutorial, there has been an interesting discussion in the R-sig-Geo mailing list about the projection of the ggmap output.

Displaying time series, spatial, and space-time data with R is available for pre-order

Two years ago, motivated by a proposal from John Kimmel, Executive Editor at Chapman & Hall/CRC Press, I started working in a book, “Displaying time series, spatial, and space-time data with R”. This book presents methods and R code for producing high-quality graphics of time series, spatial, and space-time data.

The book is already available for pre-order at CRC Press and Amazon. It will be published on April 4th, 2014. Along with the main graphics from the text, the book website offers access to the datasets used in the examples as well as the full R code.

I have spent a large amount of time and effort in this project but, now that it is finished, I can say it has been worthwhile. One of the challenges was to produce a fully reproducible book including hundreds of code chunks and graphics, and survive after several rounds of peer-reviewing. Among the tools that can create reproducible documents with R, I decided to use these gems of open-source software:

  • GNU Emacs as development environment.
  • R (of course!) with Emacs Speaks Statistics.
  • org-mode for authoring text and code.
  • LaTeX with AUCTeX to produce the final document.

If you are interested in the technical details read about writing a book with Emacs and friends.
