Description

Read image and convert to ggplot object, for use with other ggplot objects when assembling with the {patchwork} package. Can also specify a border.

Usage

fig(
  path,
  aspect.ratio = "default",
  link_dim = TRUE,
  b_col = NULL,
  b_size = 1,
  b_pos = "offset",
  b_margin = ggplot2::margin(4, 4, 4, 4)
)

Arguments

path	Path to image file.
aspect.ratio	Manually override the image's aspect ratio or set "free" to allow fig to be resized by patchwork.
link_dim	Logical, whether to lock the dimensions & aspect.ratio of the aligned plots to that of this fig.
b_col	Colour of the border line.
b_size	Size of the border line.
b_pos	Whether the border is 'offset' (expands out from figure) or 'inset' and expands inwards, partially covering up the figure.
b_margin	Margin around the fig. Use ggplot2::margin()

Value

{ggplot2} object

library(figpatch)
library(ggplot2)
