comment What is the cause of 'tearing' of polygons (artifacts) using R, ggplot and geom_polygon?
My advice would be to ask a new question complete with a subset or description of your data, with a link to this question for background information.

comment Join spatial point data to polygons in R
Then perhaps you should answer your own question with your solution. Remember, good answers are what this site is all about.

comment What can I use for Territory Management in Canada?
You can use shapefiles in Tableau - I suspect getting that to work would be less trouble than trying to get decent interactivity in R.

Something like Tableau? I like R, but sometimes you need a different tool.

comment Using R to calculate the area of multiple polygons on a map that intersect with another overlaid polygon
Thanks. I believe there is a require(scales) call in there that will do the trick.

comment Problem with merging and dissolving a shapefile in R
Use str() to get a better view of the structure of your objects. I haven't looked at it closely but if you convert your SpatialPolygons object to a data frame (which is not a spatial object) I would expect you not to be able to use unionSpatialPolygons. Generally people convert to a df to plot using ggplot towards the end of the workflow. Incidentally if the shapefile data is publicly available a link to the shapefiles would help others help you. Also, if you provide your code in one block that others can copy and paste, it helps a lot.

comment How to infer a relationship between two spatial points using R
This does strike me as being more of a statistical issue rather than a GIS question. It involves GIS but the core problem is trying to prove/disprove your hypothesis. I would try Cross Validated instead.

comment R or QGIS? Measuring elevation at points on DTM surface
Thanks for that Oscar, both those functions look promising but I can't get them to work with rgl.
