Gantt Plot

Usage

gantt_wrap(dataframe, plot.var, facet.vars = NULL, fill.var = NULL, title = NULL, ylab = plot.var, xlab = "duration.default", rev.factor = TRUE, transform = FALSE, ncol = NULL, minor.line.freq = NULL, major.line.freq = NULL, sig.dig.line.freq = 1, hms.scale = NULL, scale = NULL, space = NULL, size = 3, rm.horiz.lines = FALSE, x.ticks = TRUE, y.ticks = TRUE, legend.position = NULL, bar.color = NULL, border.color = NULL, border.size = 2, border.width = 0.1, constrain = TRUE, plot = TRUE)

Arguments

dataframe
A data frame with plotting variable(s) and a column of start and end times.
plot.var
A factor plotting variable (y axis).
facet.vars
An optional single vector or list of 1 or 2 to facet by.
fill.var
An optional variable to fill the code strips by.
title
An optional title for the plot.
ylab
An optional y label.
xlab
An optional x label.
rev.factor
logical. If TRUE reverse the current plotting order so the first element in the plotting variable's levels is plotted on top.
transform
logical. If TRUE the repeated facets will be transformed from stacked to side by side.
ncol
if an integer value is passed to this gantt_wrap uses facet_wrap rather than facet_grid.
minor.line.freq
A numeric value for frequency of minor grid lines.
major.line.freq
A numeric value for frequency of major grid lines.
sig.dig.line.freq
An internal rounding factor for minor and major line freq. Generally, default value of 1 suffices for larger range of x scale may need to be set to -2.
hms.scale
logical. If TRUE converts scale to h:m:s format. Default NULL attempts to detect if object is a cm_time2long object
scale
Should scales be fixed ("fixed", the default), free ("free"), or free in one dimension ("free_x", "free_y")
space
If "fixed", the default, all panels have the same size. If "free_y" their height will be proportional to the length of the y scale; if "free_x" their width will be proportional to the length of the x scale; or if "free" both height and width will vary. This setting has no effect unless the appropriate scales also vary.
size
The width of the plot bars.
rm.horiz.lines
logical. If TRUE the horizontal lines will be removed.
x.ticks
logical. If TRUE the x ticks will be displayed.
y.ticks
logical. If TRUE the y ticks will be displayed.
legend.position
The position of legends. ("left", "right", "bottom", "top", or two-element numeric vector).
bar.color
Optional color to constrain all bars.
border.color
The color to plot border around Gantt bars (default is NULL).
border.size
An integer value for the size to plot borders around Gantt bars. Controls length (width also controlled if not specified).
border.width
Controls border width around Gantt bars. Use a numeric value in addition to border size if plot borders appear disproportional.
constrain
logical. If TRUE the Gantt bars touch the edge of the graph.
plot
logical. If TRUE the plot will automatically plot. The user may wish to set to FALSE for use in knitr, sweave, etc. to add additional plot layers.

Gantt Plot

Value

Returns a Gantt style visualization. Invisibly returns the ggplot2 list object.

Description

A ggplot2 wrapper that produces a Gantt plot.

Note

For non-repeated measures data/plotting use gantt; for repeated measures data output use gantt_rep; and for a convenient wrapper that takes text and generates plots use gantt_plot.
