[R] help with maps : center on the dateline
Hi, I'm trying to plot a map of the pacific ocean, centered on the dateline, using the maps package. library(maps) # Basic library to draw maps library(mapdata)# Library with specialized maps library(mapproj) map(database = "world", fill = TRUE, col = 1, plot = TRUE,add=F, xlim = c(120,300), ylim = c(-20,40)) I tried several different combinations of coordinates, but whatever I try, it doesn't plot anything past the dateline. Is there a way to plot a map like the one attached, with this package ? thanks !
