This post will guide you through the best practices using R and ggplot2. Add arrow p + annotate("segment", x = 2, xend = 4, y = 15, yend = 25, colour = "pink",

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.

font_size: font size. font_family 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: Line segments and curves. geom_segment () draws a straight line between points (x, y) and (xend, yend).

A slightly different method of creating plots in R requires the ggplot2 package. We will first create a simple scatter plot using ggplot(). 17 Jul 2017 I've also decided to add the 200 m isobath to the sea panel.

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 .

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.

choices: length 2 vector specifying the components to plot. Only the default is a biplot in the strict sense.

Passed to addStepping, control whether to show each group as unique level or not.
