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 = FALSE, shareOfCircles = 0.02,
radiusMax = 0.5, valueMax = max(df[, var], na.rm = TRUE),
lgdRnd = 0, posLeg = "bottomleft",
circleCol = "#FD8D3C", baseCol = "#FFEDA0",
title = var, legend = var, author = "author", sources = "sources",
scalebar = FALSE, scalebarSize, scalebarText,
northArrow = FALSE, northArrowSize,
width = NULL, height = NULL, txtCex = NULL)
Any advice is greatly appreciated.
Many Thanks
Krish
