I have a forestplot, and my x-axis tick mark labels are spaced a bit strangely, and I would like to change it to having each tick mark be 0.1 apart from each other. Also, does anyone know how forestplot decides how the ticks are spaced?
From the forestplot
documentation ( https://cran.r-project.org/web/packages/forestplot/vignettes/forestplot.html#ticks-and-grids ), you have two options.
forestplot()
expression your ticks, eg xticks = c(-.1, -0.05, 0, .05)
xticks <- seq(from = -0.08, to = 2.50, by = 0.1)
and add it to your forestplot()
expression with xticks = xticks
