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.. To install the CRAN version use:

Passed to addStepping, control whether to show each group as unique level or not. If set to FALSE, if two groups are not overlapped with each other, they will probably be layout in … 2017-10-03 Add arrows to the lines in the plot. Instead of labeling years, use the arrow argument of the geom_path () call to show the direction of change. The arrows will point from 1996 to 2006, because that's how the data set is ordered.

I wish to add a scale bar and a north arrow outside of the plot area, at the right side of the plot legend for instance, to obtain something like this: I tried using the scalebar and north functions of the ggsn package, however these functions only allow adding scale bars and north arrows inside of the plot area. Swedish manufacturer of high quality filament for 3D printing and the only producer of filament in the Nordics. add:north offers technical polymers targeted for industrial use as well as a regular materials for consumers and businesses.

North symbols are included in the plot with the annotation_custom function, which do not works when used together with an empty call to ggplot (see last example). When it is convenient to use an empty call to ggplot, use north2 instead.

I'm not that familiar with graphing spatial data, but as a quick hack for the North arrow, the code below includes two different options: Height and width of north arrow. pad_x, pad_y: Padding between north arrow and edge of frame. rotation: Override the rotation of the north arrow (degrees conterclockwise) style: A grob or callable that produces a grob that will be drawn as the north arrow. See north_arrow_orienteering for options.

If TRUE, text will be grown as well as shrunk to fill the arrow. reflow: If TRUE, text will be reflowed (wrapped) to better fit the arrow. height: grid::unit() object giving the maximum height of the text. Defaults to 3 mm, which is the default height of gene arrows drawn with geom_gene_arrow().

A crude first attempt for an automatic scalebar addition function is listed below. Otherwise, just pass them as arguments to annotation_north_arrow(). which_north: "grid" results in a north arrow always pointing up; "true" always points to the north pole from whichever corner of the map the north arrow is in. location: Where to put the scale bar ("tl" for top left, etc.) Provides functions to add a North arrow and/or a scale bar to maps done using ggplot2. legendMap-package: North arrow and scale bar for ggplot2 graphics. in 3wen/legendMap: North arrow and scale bar for ggplot2 graphics. North arrows are added using the annotation_north_arrow() function, and scalebars can be added using annotation_scale().

Otherwise, just pass them as arguments to annotation_north_arrow(). which_north: "grid" results in a north arrow always pointing up; "true" always points to the north pole from whichever corner of the map the north arrow is in. location: Where to put the scale bar ("tl" for top left, etc.) Adding a scale bar and north arrow to a ggplot. Dear list, A common addition to any spatial plot are a north arrow and a scale bar.

which_north: "grid" results in a north arrow always pointing up; "true" always points to the north pole from whichever corner of the map the north arrow is in.

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.

When it is convenient to use an empty call to ggplot, use north2 instead. Aliases. north2. North Arrows and Scale Bars. The following code covers: how to add a north arrow and a scale bar; how to enlarge the canvas to avoid overlap; how to work with basic sf objects The direction of a zero-length arrow is indeterminate, and hence so is the direction of the arrowheads. To allow for rounding error, arrowheads are omitted (with a warning) on any arrow of length less than 1/1000 inch.

geom_gene_arrow() is a ggplot2 geom that represents genes with arrows.
