fracpoly_plot

Description

fracpoly_plot plots the best fitting fractional polynomial.

Usage

fracpoly_plot(
  fracpoly,
  degree = "both",
  xref = NULL,
  logx = FALSE,
  logy = FALSE,
  pref_x = "x",
  pref_y = "y",
  xbreaks = NULL,
  ybreaks = NULL,
  cicolour = "grey",
  betacolour = "black",
  intcolour = "grey",
  xlim = NULL
)

Arguments

fracpoly	a fracpoly object.
degree	the fractonal polyniomal degree to be plotted (options: 1, 2 and both).
xref	the reference point for the figures of binary outcomes.
logx	plot the x-axis on the log-scale.
logy	plot the y-axis on the log-scale.
pref_x	the prefix for the x-axis.
pref_y	the prefix for the y-axis.
xbreaks	breaks in the x-axis.
ybreaks	breaks in the y-axis.
cicolour	colour of the 95% confidence intervals.
betacolour	colour of the regression line.
intcolour	colour of the intercept line.
xlim	x-axis limits.

Value

fractional polynomial plot.

Examples

# Data
y <- rnorm(5000)
x <- rnorm(5000, 10, 1)
c1 <- rbinom(5000, 1, 0.5)
c2 <- rnorm(5000)
study <- c(rep("study1", 1000), rep("study2", 1000), rep("study3", 1000), rep("study4", 1000), rep("study5", 1000))
covar <- data.frame(c1 = c1, c2 = c2, study = study)

# Analyses
res <- fracpoly(y = y, x = x, covar = covar, family = "gaussian")
fracpoly_plot(res)
