2 Apr 2018 When I have multiple layers to plot, I use to write my ggplot layers as is: ggplot() + In that case, your scalebar continues to work but not the north arrow. Maybe can you add a test whether this is a {sf} object or

x: an object returned by pca(), prcomp() or princomp(). choices: length 2 vector specifying the components to plot. Only the default is a biplot in the strict sense. scale: The variables are scaled by lambda ^ scale and the observations are scaled by lambda ^ (1-scale) where lambda are the singular values as computed by princomp.

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. 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.

R package to add north symbols and scale bars to maps created with ggplot or ggmap. View on GitHub. The ggsn package improves the GIS capabilities add_gg() adds ggplot2 functions (e.g. to add layers such as points, polygons, lines, add_northarrow() adds a north arrow to the animation frames created with In addition to maps, rayshader also allows the user to translate ggplot2 You can also easily add a water layer by setting water = TRUE in plot_3d() (and setting Adds an arrow indicating the direction of play to a ggplot plot direction_label find an R function to add a scale bar and a North arrow on a map, using ggplot().

You can change the symbol by changing symbol to any integer from 1 to 8.

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.

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. The arrow () function takes two arguments: The first is length, which can be specified with a unit () call, which

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.

The north arrow is added to the layout. PCA Biplot with ggplot2. PCA Biplot with. 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.
