L.plot: Times of Record Plot

Description

This function builds a ggplot object to display the upper and lower record times for both forward and backward directions.

Usage

L.plot(
  X,
  all = TRUE,
  record = c("upper", "lower"),
  point.col = "grey23",
  point.alpha = 0.8,
  line.col = "grey95"
)

Value

A ggplot object.

Arguments

X

A numeric vector, matrix (or data frame).

all

Logical. If TRUE (the default) the four types of record are displayed.

record

If all = FALSE, a character string indicating the type of record to be calculated, "upper" or "lower".

point.col, point.alpha

Colour and transparency of the points.

line.col

Colour to plot lines.

Details

The function can be applied to plot the record times in a vector (if argument X is a vector) or to plot and compare the record times in a set of vectors (if argument X is a matrix). In the latter case, the approach to obtain the record times is applied to each column of the matrix.

If all = TRUE, a matrix of four panels is displayed for upper and lower records, and for the forward and backward (series_rev) directions. Otherwise, only one type of forward record is displayed.

An example of use of a plot with similar ideas is shown in Benestad (2004, Figures 3 and 8).
