Plot a map area cross Longitude 180

[Ruiqi-CUB]

Hi there,

I have a map area that I would like to plot across longitude 180 as shown below:

Is there a way to do it? Thanks!

here is my current code:

plot(snail.phymap2,
     xlim=c(-180,180),ylim=c(-90,90),pts=FALSE,
     ftype="i",fsize=0.8,map.bg="lightgreen",
     lty="solid",colors="darkblue",
     delimit_map=TRUE)
