[R-sig-Geo] aligning tick maks with coord_map and ggplot

[zuzana zajkova]

Hi Andy,

try the geom_sf (not sure now but probably you would need the dev. version
of ggplot2).
Check http://ggplot2.tidyverse.org/reference/ggsf.html

library(maps)
world1 <- sf::st_as_sf(map('world', plot = FALSE, fill = TRUE))
ggplot() + geom_sf(data = world1)

Projected:
ggplot() +
  geom_sf(data = world1, colour="gray50", fill="gray50") +
  coord_sf(crs="+proj=ortho +y_0=0 +lon_0=-110 +lat_0=40", xlim=c(-2000000,
500000), ylim=c(-1800000, 2000000)) +
  scale_x_continuous(breaks=seq(-140, -100, 10)) +
  scale_y_continuous(breaks=seq(10, 60, 10))

Best,

Zuzana
