This function computes LTT plots for a set of trees & plots a (1-\(\alpha\))-percent CI by various methods.
ltt95(trees, alpha=0.05, log=FALSE, method=c("lineages","times"),
mode=c("median","mean"), ...)
# S3 method for ltt95
plot(x, ...)is an object of class "multiPhylo" containing a list of phylogenetic trees.
confidence level.
logical value indicating whether or not to plot on the log-scale.
plot the CI on the number of lineages given time ("lineages"); or on times given a number of lineages ("times").
plot the median or mean LTT.
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.
This function creates a plot and invisibly returns an object of class "ltt95".
