[R-sig-Geo] lollipop plot via plotKML

[Beaulieu, Jake]

Hello,
I would like make a lollipop plot displaying soil characteristics using plotKML, similar to Fig.3 in Hengl's 2015 plotKML paper in JSS.

I'm using the eberg dataset in the plotKML package as a demo.  All points need to be plotted the same size and the image must include line segments joining the points to their projection on the xy plane.  Here is my progress so far.

> plotKML(eberg["CLYMHT_A"], colour_scale=rep("#FFFF00", 2), points_names="", size=1, altitude = CLYMHT_A)
Error in `[.data.frame`(obj at data, , deparse(size)) :
  undefined columns selected

I'm having issues with both the size and altitude arguments.  Any suggestions?

Thanks!
