search for: choropleth

Hi all, I would like to use R in order to generate a Heatmap/Choropleth overlaid on the UK map. Can someone please help with finding the right package/code? Any help is much appreciated. Best, Reza [[alternative HTML version deleted]]

Hi guys i need some help to build choropleth. Basically i am trying to colour regions on the map by population. I possess the shape file of the country, and also the population data, however, i am having trouble to create the plot, below is my code: population=read.csv("nz2.csv") population names(population) nz=readShapeSpatia...

...sically what im after is to illustrate probabilities for each of my geographic units for my shape file with breaks at each .1, using gray or any other color for that matter.

...5. I have carefully followed a number of tutorials and can reproduce those, and can also produce scatter and bubble plots of my data (using long and lat coordinates to place the pch and bubbles). What the tutorials (apparently) don't cover is how to key the data with the shape files to produce choropleth maps. My keys for states are like AK, AL, AR, etc., and my keys for the zip3 are like 902,303, 465, etc. The examples seem to use data that's part of the shape file (such as POPULATION), but my data is in separate files. How do I connect the ID in the shape files with the key in the data files?...

Hola! Quiero empezar a georeferenciar en mapas con R. En blogs se encuentra bastante información pero veo que no hay unanimidad respecto a las librerías a utilizar ni tampoco la información es muy clara ni abarcativa. ¿Alguno/a trabaja con mapas en R y me puede indicar por donde encarar? En principio mi interés es realizar mapas sencillos con información por provincias y departamentos de

Hello useRs, I am announcing the release of my first package, usmap ( http://cran.r-project.org/package=usmap). "usmap" is a package to aid in the creation of US choropleths that include Alaska and Hawaii. It is still in its early stages (v 0.1.0) but I hope to improve it with added functionality over time. Features can be seen in the vignettes here: https://cran.r-project.org/web/packages/usmap/vignettes/introduction.html https://cran.r-project.org/web/packages/usma...

If I want to create a heat map where I have a graphic of a US State with county borders, how do I import and work with the graphic image? The reason I would like to use R is so I can then define color parameters and quickly produce heat maps that correspond to various data in dataframes.   Thanks.

Apologies in advance from an R newbie if this is a dumb question. Is it possible to produce choropleth maps in R? I gather from some nice research papers on the AT&T (sorry, Lucent) S web site that in S (and S Plus) there is a map() function which uses arrays of polylines and regions to draw map borders and then fill them with patterns or shades according to some scalar quantity. We currently pr...

Anybody interested in the S maps library for R? I have ported a limited version of the software for a Unix platform, and would be happy to make it available for anybody interested. If there is a lot of interest then I will submit it to CRAN. I know that Ross Ihaka is working on a new version for R, which does not have some of the limitations of the original S version. My version does not do
