I want to overlay a small inset map on top of another map, but I can't figure out how to do it. For example, here are two different maps: # map 1 - Ohio map("state", region= "ohio") # map 2 - US with Ohio darkened map("state") map("state", region="ohio", fill=T, add=T) I would like to add map 2 as a small inset in the corner of map 1. I have tried: map("state", region=...

Helpful for TTM-based drivers. We could completely drop that if we use the same structure inside TTM as well. Additional to that which driver is going to use this?

Hi, I would like to plot a map of US counties using different colors. map() seems to be the function to use, e.g. library(maps); map('usa'); map('county', 'colorado', add=T,fill = T, col=c(1:5)) plots Colorado counties using colours 1 to 5. However, I want each color to represent a certain value - a value to be picked from a data frame. This code should show a correspoding map at the level of sta...

This patch series proposes two new filters. * truncate: This can truncate, extend, round up or round down the size of a plugin/device. A typical usage is to fix the qemu problem that it can only handle devices which are a multiple of 512-bytes: nbdkit --filter=truncate random size=500 round-up=512 This will serve a virtual device with size 512 bytes. Reading from the last 12 bytes will
