Plot an LRP fit (publication style) — plot.lrp

Draws the observed points, the fitted broken line, dotted guides to the breakpoint and the plateau-model annotations, in the layout used in plot-size articles: the model block (equations and \(R^2\)) centred at the top and Xo/CVxo next to the breakpoint. Axis limits come from the data.

Usage

# S3 method for class 'lrp_fit'
plot(

  cond_word = "if",
  digits_coef = 3,
  digits_stat = 2,
  point_size = 2.3,
  line_size = 0.8,
  point_colour = "black",
  line_colour = "black",
  bp_colour = "red",
  base_size = 12,
  label_size = 4.6,
  title_size = NULL,
  family = "sans",
  theme = NULL,
  save = FALSE,
  file = NULL,
  format = c("tiff", "png", "jpeg", "pdf", "eps"),
  dpi = 300,
  width = 18,
  height = 12,
  units = "cm",
  compression = "lzw",
  ...
)

Arguments

x: an object of class "lrp_fit".
title: plot title.
annotate_model: logical; draw the model equations and statistics.
xlab, ylab: axis titles. xlab = NULL uses "Plot size (m^2)".
decimal_mark: decimal separator for the annotations, "." or ",".
cond_word: conditional word in the equations (e.g. "if" or "se").
digits_coef, digits_stat: decimals for the coefficients (a, b) and for the statistics (Xo, CVxo, R2).
point_size, line_size: sizes of the points and the fitted line.
point_colour, line_colour, bp_colour: colours of the points, the fitted line and the breakpoint marker.
base_size: base font size for the theme; axis titles and text scale from it.
label_size: size of the annotation text (equations, Xo, CVxo).
title_size: size of the plot title. NULL uses base_size.
family: font family for the theme and annotations.
theme: optional ggplot2 theme object used instead of the package default (the shared trialSizing theme); the title_size tweak is applied on top.
save: logical; if TRUE, write the figure to disk (default FALSE).
file: output file name; if NULL, derived from title.
format: one of "tiff", "png", "jpeg", "pdf", "eps". TIFF/PDF/EPS are preferred for journals; TIFF is written with LZW compression.
dpi: resolution for raster formats.
width, height, units: figure size.
compression: TIFF compression (default "lzw").
...: ignored.

Value

A ggplot object (invisibly when saved).
