The insanely productive elf-lord, @quominus put together a small package (triebeard) that exposes an API for radix/prefix tries at both the R and Rcpp levels. I know he had some personal needs for this and we both kinda need these to augment some functions in our iptools package. Despite triebeard having both a vignette and… Continue reading

New viridis & colorbrewer palettes for ipv4-heatmap

It’s no seekrit that I :heart: Hilbert curve heatmaps of IPv4 space. Real-world IPv4 maps (i.e. the ones that drop dots on the Earth) have little utility, but with Hilbert curves maps of IPv4 space many different topologies can be superimposed (from ASNs to—if need be—geographic locations). Plus, there’s more opportunity to find patterns by… Continue reading

However, #rstats questions exist in other Stack watering holes, like the Geographic Information Systems Stack Exchange. Cross Validated and the fledgling Data… Continue reading
