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.

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.)

The north arrow can be locked to prevent changes from being made by checking the Locked check box. The default is unlocked. The map frame a north arrow is associated with can be changed by choosing a new map frame from the drop-down list in the North I’ll also assume you’ve analysed your data so you know what annotations you want to add. Faceting is a very useful feature of ggplot which allows you to efficiently plot subsets of your data next to each other. In this example the data are the wing lengths for males and females of two imaginary species of butterfly in two regions, north and ggplot(plotDF, aes(x, y)) + geom_segment(aes(xend = dplyr:: lead(x), yend = dplyr:: lead(y)), arrow = arrow()) If folks agree that this change is worth making, I'm not sure if it would be cleaner to implement this by passing a vector of arrow objects to the geom's arrow argument, or through changes to the arrow function. 2021-04-09 · 18.2.8.

Add north arrow ggplot

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. 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. 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.) Examples Swedish manufacturer of high quality filament for 3D printing and the only producer of filament in the Nordics.

a ggplot. x: position at x axis. y: position at y axis. label: text label. space: a small space between arrow and text. vjust: vertical adjustment, set to 0 to align with the bottom, 0.5 for the middle, and 1 (the default) for the top. seg_len: length of the arrow segment. arrow_len: length of the arrow. arrow_type: type of the arrow. font_size: font size. font_family

prettymapr, vcd, ggsn, or legendMap). We introduce here the package ggspatial, which provides easy-to-use functions… scale_bar that allows to add simultaneously the north symbol and a scale bar into the ggplot map. ggsn 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: 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).

The north arrow can be hidden by unchecking the Visible check box. The default is visible. The north arrow can be locked to prevent changes from being made by checking the Locked check box. The default is unlocked. The map frame a north arrow is associated with can be changed by choosing a new map frame from the drop-down list in the North

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(). These functions are “spatial-aware”, meaning they know where north is and what the distance is across the plot. North arrow and scale bar for ggplot2 graphics.

It looks like map.scale and north.arrow are designed to work with base graphics, but ggplot uses grid graphics. 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. 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.

A common addition to any spatial plot are a north arrow and a scale bar. I've searched online for a straightforward way to add those to a ggplot plot. I then decided to give a go myself.

8 Apr 2015 are now more than 5000 official add-on packages, allowing R to tackle for visualising data, beyond the base graphics. ggplot2 also has to create both the north arrow and scale bar since they are, in effect, data tha

I've tried many solutions, some of which look like this: trying to add scale bar. map.scale <- ggmap (new) + (ggmap, extent = "normal", maprange = FALSE) %+% sites.data + geom_point (aes (x = lon, y = lat, colour = colour)) + geom_text After some research on the Internet, I gave up trying to find an R function to add a scale bar and a North arrow on a map, using ggplot(). So, I would like to present you what I have come up with.

legendMap 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.
