Utility to plot points on an OpenStreetMap with R providing a dynamic and interactive Geo Mapping experience.
OpenStreetMapR is a free and open source package for R providing an interactive mapping experience with Open Street Maps and Leaflet.js. You can install it from R with the following:
library(devtools)
install_github('OpenStreetMapR', 'greentheo')To get started using OpenStreetMapR, simply create a data frame and use the plot funcitonality
df = data.frame(lat=runif(10, 38,40), long=-runif(10, 104,106),
size=runif(10)*20, color=sample(rainbow(3), 10, replace=TRUE),
line=sample(1:3, 10,replace=TRUE))
OSMMap(df)
OSMMap(df, size='size', color='color')And the best part is, you can overlay different groups of layers and markers. Open Street Map and Leaflet provide functionality to turn the layers on and off.
dualMap = (addLayers(OSMMap(df, size='size', color='color'),
linePlot))
plot(dualMap)You can also include the plots as part of R HTML and knitr with the following:
print(OSMMap(df, size='size', color='color'))For more usage examples see 'package/inst/examples/' or take a look at this page http://greentheo.github.io/OpenStreetMapR/ .
