In hypercompetent/xstitch: Cross-stitch pattern generation.

Description

Add gridding, arrows, and plotting theme for a cross-stitch plot

Usage

add_grid(p, x_range = c(0, 100), y_range = c(0, 100), pad = 5,
  center_arrows = TRUE, base_size = 10, base_family = "")

Arguments

p	The plot object to use.
x_range	The range of the x values in the plot. Default is c(0,100), but should be entered per-project.
y_range	The range of the y values in the plot. Default is c(0,100), but should be entered per-project.
pad	Stitch padding to add around the edges of the pattern. Default is 5.
center_arrows	Logical, whether or not to include arrows pointing to the center stitch. Default is TRUE.
base_size	Base font size for the plot theme. Default is 10. See ?ggplot2::theme() for more information.
base_family	Base font family for the plot theme. Default is "", which will use system defaults.

Value

A ggplot2 object with grid, optional arrows, and theme applied.

Examples

library(ggplot2)

vmat <- floor((volcano - 100)/30)
vdf <- reshape2::melt(vmat)

p <- ggplot() +
  geom_point(data = vdf,
             aes(x = Var1,
                 y = Var2,
                 pch = as.factor(value),
                 color = as.factor(value)))

add_grid(p,
         x_range = c(1,87),
         y_range = c(1,61),
         center_arrows = T)
