Custom ggplot2 Theme Based on ggprism

A customizable ggplot2 theme built on top of ggprism palettes, with additional control over grid lines, panel spacing, plot margins, and axis text angle.

Usage

theme_my(
  palette = "black_and_white",
  base_size = 14,
  base_family = "sans",
  base_fontface = "bold",
  base_line_size = base_size/14,
  base_rect_size = base_size/14,
  axis_text_angle = 0,
  border = TRUE,
  legend.position = "right",
  panel.grid = element_line(color = "lightgray", linetype = "dashed", linewidth = 0.1),
  panel.grid.minor = element_line(color = "lightgray", linetype = "dashed", linewidth =
    0.1),
  panel.spacing = unit(0, "pt"),
  plot.margin = NULL
)
