Re: [R] plotting with varying dot sizes

I think I located the problem. the data frame associated with my spatial object (Insitu_sp) contains some NAs. And in this case, the function plot does not like NAs. It simply behaved strangely. The code below did the trick : idx = is.na(Insitu[,"SPM"]) ptsize = 0.35*(sqrt(Insitu[!idx,"SPM"])+1) p
