Create a forest plot object (fobj)

First step to generate a forest plot. Generates a fobj that can be plotted.

Usage

genfobj(
  layout,
  dat,
  obs = NULL,
  lwidths = NA,
  lheights = NA,
  y.at = NA,
  ylim = NA
)

layout: layout of the plot, character vector with 't' (text), 'f' (forest), 's' (strip), 'b' (boxplot) or 'd' (density plot).
dat: data frame that should be plotted
obs: Optional data frame with the observations for the boxplot. Required of layout includes 'b' or 'd'.
lwidths: Optional numeric vector with the relative widths of the columns. Must have the same length as layout.
lheights: Optional numeric vector of length 3 with the relative heights of header, main panel and footer.
y.at: Optional numeric vector with the position of the rows. Usually not required.
ylim: Optional limits of the rows. Usually not required.

a forest plot object of class 'fobj'


fobj<-genfobj(layout = c("t","t","t","t","t","t","f","t"),
  dat = forplotdata,
lwidths = c(0.8,0.4,0.6,0.4,0.6,1,1,0.5))
plotfobj(fobj)
