Text is the most common kind of annotation. It allows to give more information on the most important part of the chart. Using ggplot2, 2 main functions are available for that kind of annotation:. geom_text to add a simple piece of text; geom_label to add a label: framed text; Note that the annotate() function is a good alternative that can reduces the code length for simple cases.

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().

The Picture and the North Arrow Items¶.

I often do faceted plotting with ggplot. However, if using facets with annotations, such as annotation_scale and annotation_north_arrow, appear on all facets. How would it be possible to make them appear only once, other than using patch

ggplot (geopotential, aes (lon, lat)) + geom_contour (aes (z = gh.z)) + geom_vector (aes (angle = atan2 (dlat (v), dlon (u, lat)) * 180 / pi, mag = Mag (v, u)), skip = 1, pivot = 0.5) + scale_mag () I often do faceted plotting with ggplot. However, if using facets with annotations, such as annotation_scale and annotation_north_arrow, appear on all facets. How would it be possible to make them appear only once, other than using patch Provides functions to add a North arrow and/or a scale bar to maps done using ggplot2. How to Install devtools::install_github("3wen/legendMap") Examples Draws a north arrow on a map.

The approach also uses the sf package for spatial data reading and handling, cowplot to arrange The main map can also be enhanced with the north arrow and

location: Where to put the scale bar ("tl" for top left, etc.) Examples Finally you can add a north arrow using: ggsn::north(sjer_roads_df, scale = .08) You can adjust the size and location of the north arrow as well. 2018-10-25 · scale_bar that allows to add simultaneously the north symbol and a scale bar into the ggplot map. Five arguments need to be set manually: lon , lat , distance_lon , distance_lat , and distance_legend .

ggplot2. Produces a ggplot2 variant of a so-called biplot for PCA (principal component analysis), but is more flexible and more appealing than the base R biplot () function. 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().
