R Help,
I posted a question on StackOverflow yesterday regarding an issue I've been having with the RgoogleMaps packages' displaying of axes. Here is the text of that submission: http://stackoverflow.com/questions/6258408/rgooglemaps-axes "I can't find any documentation of the following problem I'm having with the axis labels in RGoogleMaps: library(RgoogleMaps) datas <-structure(list(LAT =c(37.875,37.925,37.775,37.875,37.875), LON =c(-122.225,-122.225,-122.075,-122.075,-122.025)), .Names=c("LAT","LON"),class="data.frame", row.names =c(1418L,1419L,1536L,1538L,1578L)) # Get bounding box. boxt <-qbbox(lat =datas$LAT,lon =datas$LON) MyMap<-GetMap.bbox(boxt$lonR,boxt$latR,destfile ="Arvin12Map.png", maptype ="mobile") PlotOnStaticMap(MyMap,lat =datas$LAT,lon =datas$LON, axes =TRUE,mar =rep(4,4)) When I run this on my computer the horizontal axis ranges from 300W to 60E, but the ticks in between aren't linearly spaced (300W, 200W, 100W, 0, 100E, 160W, 60W). Also, the vertical axis moves linearly from 300S to 300N. It seems that no matter what data I supply for datas, the axes are always labeled this way. My question is: 1. Does this problem occur on other machines using this code? 2. Does anyone have an explanation for it? and 3. Can anybody suggest a way to get the correct axes labels (assuming these are "incorrect", but maybe i'm somehow misinterpreting the plot!)? Thank you for your time." There has been no answer other than that I ought to contact the package maintainer. Since it would be nice to have a publicly displayed solution, I opted to post here first before doing so. Does anyone have any insight to share?
