ltt95: Creates a (1-$\alpha$)-percent CI for a set of LTTs

Description

This function computes LTT plots for a set of trees & plots a (1-$\alpha$)-percent CI by various methods.

Usage

ltt95(trees, alpha=0.05, log=FALSE, method=c("lineages","times"), mode=c("median","mean"), ...) "plot"(x, ...)

Arguments

trees
is an object of class "multiPhylo" containing a list of phylogenetic trees.
alpha
confidence level.
log
logical value indicating whether or not to plot on the log-scale.
method
plot the CI on the number of lineages given time ("lineages"); or on times given a number of lineages ("times").
mode
plot the median or mean LTT.
x
object of class "ltt95" for plotting method.
...
optional arguments to be used by ltt95 or the plotting method. So far, res gives the number of time-steps (defaults to res=100. xaxis ("standard", "negative", or "flipped") determines the scale (time from the root, time back from the present, or time from the present) of the x-axis of the plot.

Details

This function creates a plot and invisibly returns an object of class "ltt95".
