Pick tick positions in the (already-transformed) xlim space.
make_ticks(at = NULL, xlim, refline = 1, x_trans = "none")A vector of tick coordinates in the transformed space.
Numerical vector, create ticks at given values.
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.
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.
For x_trans in "none" / "scientific" this delegates to
pretty. For "log" / "log2" / "log10"
it converts xlim back to the original scale, runs
log_pretty to get base-aware ticks (e.g. 0.1, 1, 10
rather than 0.22, 0.61, 2.72), and re-applies the transform. The
reference line value is included as a tick when it falls inside the range,
so forest plots always label their visual anchor.
