mapcircles help

Dear Sirs/Madame,


I have a spatial polygons data frame and want to map proportional circles on it. I have tried using the map circles function in rCarto as seen below but it doesn't seem to work an continues to show errors. Do I need to convert the spatial polygons data frame to a shapefile if so I would I do this?



mapCircles(shpFile, shpId, df, dfId, var,
           fixedNorm =ALSE, shareOfCircles = 0.02,
           radiusMax =.5, valueMax = max(df[, var], na.rm = TRUE),
           lgdRnd =, posLeg = "bottomleft",
           circleCol =#FD8D3C", baseCol = "#FFEDA0",
           title =ar, legend = var, author = "author", sources = "sources",
           scalebar =ALSE, scalebarSize, scalebarText,
           northArrow =ALSE, northArrowSize,
           width =ULL, height = NULL, txtCex = NULL)



Any advice is greatly appreciated.


Many Thanks

Krish

Hi,
As maintainer of the rCarto package, my advice would be to switch to the
cartography package (of which I am also maintainer) and the
propSymbolsLayer function in it. Examples and the vignette will help you
through the mapping process.

My turn to ask for an advice:
rCarto was my first package and after a while we decide to build an other,
better, thematic mapping package (i.e. the cartography package).
cartography is much more R-ish in its use of the graphic device, offers
more kinds of maps and has more options to customize the maps.
So my question is: what should I do with rCarto? Remove it from CRAN?
Deprecate all functions in it? Add a visible comment to incite users to
switch to cartography?

Any advice is greatly appreciated.
Thanks,
Tim
