This function computes LTT plots for a set of trees & plots a (1-\(\alpha\))% CI by various methods. (See ltt
for more details.)
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. Defaults to alpha=0.05
. alpha=0
will mean that the interval around all trees in the set will be plotted.
logical value indicating whether or not to plot on the semi-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; 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
.
