How to switch to a map that is centered on the China instead of the default set in R ? -
i have been using r plot world map , want switch map centered on pacific ocean , splits atlantic make data plot easier.
but default set of r this:
map("world")
and want map this:
i have tried of r worldmap option "orientation" though says " orientation vector c(latitude, longitude, rotation) describing map should centered , clockwise rotation (in degrees) center. " still not use example following command produce this:
map("world",orientation=c(35,104,0)) warning: in map("world", orientation = c(35, 104, 0)) : projection failed data
the result this:
the result strange. how can right picture 2 have shown? thank you.
your example picture seems centered around 0 lat, 150 lon. following seems generate example picture:
library(maps) map("world",orientation=c(90, 150,0), projection="mollweide", wrap=true)
for reason appears need add 90 longitude.
