[R-sig-Geo] New version of plotGoogleMaps ( now plot STDIF and STFDF data)

[Ross Dwyer]

Hi Milan,

The new package looks great. Any plans to generate animations from spacetime objects on a Google platform such as Maps or Earth?

I would love to see something similar to Google's Public Data Explorer/google motion charts become available within an R package (see below links)...

Subject: [R-sig-Geo] New version of plotGoogleMaps ( now plot STDIF and STFDF data)

Dear all,


I have just uploaded to CRAN a new version plotGoogleMaps.


Significant changes in plotGoogleMaps are listed below:

* Now plotGoogleMaps plot spacetime STDIF and STFDF data;

See example in vignette.

* Some bugs in plotting pie charts over Google Maps are repaired - function segmentGoogleMaps;

* Functions provide data to be plotted in similar way like spplot maps; pieSP, vectorsSP, colors like in plotGoogleMaps (PolyCol) and similar are now in package.

  Example:

# plotGoogleMaps plot

library(plotGoogleMaps)

data(meuse)
coordinates(meuse)<-~x+y # convert to SPDF
proj4string(meuse) <- CRS('+init=epsg:28992')

m<-segmentGoogleMaps(meuse, zcol=c('zinc','dist.m'), mapTypeId='ROADMAP', filename='myMap4.htm', colPalette=c('#E41A1C','#377EB8'), strokeColor='black')

# spplot

pies<-pieSP(meuse,zcol=c('zinc','dist.m'), max.radius=100)

pies$pie2=rep(1:2,155)

spplot(pies, 'pie2', col.regions=c('#E41A1C','#377EB8') )

# plot

cols=PolyCol(pies$pie2,colPalette=c('#E41A1C','#377EB8') )$cols

plot(as(pies,'SpatialPolygons'), col=cols)

#plotKML

library(plotKML)

plotKML(pies, colour='pie2', colour_scale=cols)


All major changes are documented in the vignette.

Happy testing,
