In kevinlzheng/statemaps: Collective Functions to Perform Generalized Linear Model Graphs

Usage

clipper(geoobj, state, margin = 0.1)

Arguments

geoobj	A geo-object,
state	a state abbrebriation, e.g. "CA",
margin	margin added to maps, \item yNameyName for making equation labels

This function performed basic clip function to geoobj and add a polygon outside line clip1 <- clipper(geoobj = us.states, state = unique(us.states$STATE_ABBR)) # USA map with projection plot(clip1,col = "red", border ="black", xpd =F) clip2 <- clipper(geoobj = us.states, state = "CA") # CA map with nhd2 projection plot(clip2, col ="blue") clip3 <- clipper(geoobj = us.counties, state = as.vector(unique(us.counties$STATE_ABBR))) # USA map with projection plot(clip3,col = "red", border ="black", xpd =F)
