Line segments and curves. geom_segment () draws a straight line between points (x, y) and (xend, yend). geom_curve draws a curved line. See the underlying drawing function grid::curveGrob () for the parameters that control the curve.

Also, I tried spplot but despite I like the label axis format I can't add a scalebar and a north arrow, perhaps because of the raster's longlat projection. Share.

Adding a north arrow. Currently the default north command from the ggsn package doesn’t work properly, so we can’t just do map_FEOW + north(). Instead north2() has to be used as an alternative. You can change the symbol by changing symbol to any integer from 1 to 8.

North arrows are added using the annotation_north_arrow () function, and scalebars can be added using annotation_scale (). These functions are “spatial-aware”, meaning they know where north is and what the distance is across the plot.

ggplot_pca( x , choices = 1:2 , scale = 1 , pc.biplot = TRUE , labels = NULL , labels_textsize = 3 , labels_text_placement = 1.5 Drawing gene arrows with geom_gene_arrow().

The arrows will point from 1996 to 2006, because that's how the data set is ordered. The arrow () function takes two arguments: The first is length, which can be specified with a unit () call, which The topographic north arrow can be inserted on any map layout. Verify that the map is in layout view.

The ggsn package improves the GIS capabilities of R, making possible to add 18 different north symbols and scale bars in kilometers, meters, nautical miles, or statue miles, to maps in geographic or metric coordinates created with ggplot or ggmap. Adding a north arrow. Currently the default north command from the ggsn package doesn’t work properly, so we can’t just do map_FEOW + north(). Instead north2() has to be used as an alternative. You can change the symbol by changing symbol to any integer from 1 to 8.
