linemap
: Create Maps Made of LinesThe package contains two functions: linemap()
and getgrid()
linemap()
linemap()
displays a map made of lines using a data frame of gridded data.
library(linemap)
library(sf)
data("popOcc")
data("occitanie")
opar <- par(mar=c(0,0,0,0), bg = "ivory2")
plot(st_geometry(occitanie), col="ivory1", border = NA)
linemap(x = popOcc, var = "pop", k = 2.5, threshold = 50,
col = "ivory1", border = "ivory4", lwd = 0.6, add = TRUE)
par(opar)
getgrid()
getgrid()
transforms a set of polygons (sf
objects) into a suitable data frame for linemap()
.

data("bretagne")
data("france")
plot(st_geometry(bretagne))
bret <- getgrid(x = bretagne, cellsize = 2000, var = "POPULATION")
