make_xaxis: Create x-axis

Description

This function used to x-axis for the forest plot.

Usage

make_xaxis(
  at,
  at_minor = NULL,
  xlab = NULL,
  x0 = 1,
  x_trans = "none",
  ticks_digits = 1,
  gp = gpar(),
  xlab_gp = NULL,
  xlim
)

Value

A grob

Arguments

at

Numerical vector, create ticks at given values.

at_minor

Numerical vector, create ticks at given values without label.

xlab

X-axis label, see set_labs.

x0

Position of vertical line for 0 or 1.

x_trans

Scale of the axis, one of "none" (default), "log", "log2" or "log10". Use "log" if the values are exponential, e.g. odds ratios or hazard ratios. The default reference line of forest is 1 for log scales and 0 otherwise.

ticks_digits

Number of digits for the tick labels. If an integer is given, for example 1L, trailing zeros after the decimal mark are dropped. Give a double, for example 1, to keep them. By default the number is calculated from the tick positions. Use a list to mix the two between CI columns, as a vector makes them all double.

gp

Graphical parameters for arrow.

xlab_gp

Graphical parameters for xlab.

xlim

Limits for the x-axis as a vector of length 2, i.e. c(low, high). By default the minimum and maximum of the lower and upper values are used.
