ltt95R Documentation

Creates a (1-\alpha)% CI for a set of LTTs

Description

This function computes LTT plots for a set of trees & plots a (1-\alpha)% CI by various methods. (See ltt for more details.)

Usage

ltt95(trees, alpha=0.05, log=FALSE, method=c("lineages","times"),
   mode=c("median","mean"), ...)
## S3 method for class 'ltt95'
plot(x, ...)

Arguments

trees

is an object of class "multiPhylo" containing a list of phylogenetic trees.

alpha

confidence level. Defaults to alpha=0.05. alpha=0 will mean that the interval around all trees in the set will be plotted.

log

logical value indicating whether or not to plot on the semi-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; lend determines the line end type (as in par); shaded determines whether to plot the (1-\alpha)% CI using dotted lines (if FALSE) or shading (if TRUE); and bg is the background color for shading if shaded=TRUE.

Details

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