Hi, I'm trying to overlay a geographical map with a heat map by following the directions on http://pages.stern.nyu.edu/~achinco/programming_examples/Example__PlotGeographicDensity.html.
However, the smaller my zoom level (the farther I zoom out), the more white horizontal lines I have interspersed in the tiled data after calling geom_tile. Is there any way around this? I tried setting the image to panel.background, but found it impossible to scale back to the original heat map matrix. -- View this message in context: http://r.789695.n4.nabble.com/geom-tile-rendering-problems-tp3924100p3924100.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
