worldLLhigh {PBSmapping} | R Documentation |
PolySet of polygons for the global shorelines.
data(worldLLhigh)
Data frame consisting of 4 columns: PID
= primary polygon ID,
POS
= position of each vertex within a given polygon, X
= longitude coordinate, and Y
= latitude coordinate. Attributes:
projection = "LL"
.
In R, the data must be loaded using the data
function.
