add_northarrow.Rd This function adds a north arrow to the animation frames created with frames_spatial.

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. A crude first attempt for an automatic scalebar addition function is listed below.

Inset maps enable multiple places to be shown in the same geographic data visualisation, as described in the Inset maps section (8.2.7) of our open source book Geocomputation with R. The topic of inset maps has gained attention and recently Enrico Spinielli asked inset maps could be created for data in unusual coordinate systems:. Speaking of insets, do you know of any ggplot2 examples with an

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:

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.

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(). geom_gene_arrow() is a ggplot2 geom that represents genes with arrows. The start and end locations of the genes within their molecule(s) are mapped to the xmin and xmax aesthetics respectively.

•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.)

Dear list, 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 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.

geom_gene_arrow() draws genes as arrows, allowing gene maps to be drawn. Usage 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(). 2019-08-07 · So long story short, this is my solution to adding a north arrow and scale bar, but I admit better solutions probably exist. So basically I just build my own polygons and labels to add into the map where I want.
