- x
A gantt object.
- xlim
optional range of time axis; if not provided, the range of times
in x
will be used.
- time.format
format for dates on time axis; defaults to 3-letter
month.
- time.labels.by
suggested label increment on time axis, e.g.
time.labels.by="2 months"
to get a two-month interval. If not
supplied, the axis will be generated automatically.
- time.lines.by
suggested interval between vertical grid lines on the
plot, e.g. time.lines.by="1 week"
for weekly. If not supplied, the
grid will be generated automatically.
- event.time
vector of event times, e.g. conferences, whose time cannot
be altered.
- event.label
vector of character strings holding event names.
- event.side
side for event labels.
- col.connector
colour of (optional) connectors between items.
- col.done
colour of work that has been done already. This may be a
vector of colours, one for each item in the gantt table.
- col.notdone
colour of work that has not been done yet. This may be a
vector of colours, one for each item in the gantt table.
- col.eventLine
colour of event lines; may be a vector.
- col.event
colour of event labels; may be a vector.
- cex.event
expansion factor for event labels; may be a vector.
- font.event
font for event labels; may be a vector.
- lty.eventLine
line type for event lines; may be a vector.
- lwd.eventLine
line width for event lines; may be a vector.
- bg
background colour for plot.
- grid.col
colour for grid.
- grid.lty
line type for grid.
- ylabels
A list with elements col
for colour,
cex
for character-expansion factor, font
for font, and justification
for the placement in the margin (0
means left-justified, and 1
means right-justified. (NOTE: left-justification works poorly in RStudio, but
properly in other systems.)
It usually makes sense for the elements in ylabels
to be vectors of the same
length as the topic list. However, shorter vectors are permitted, and they lengthened by
copying the default values at the end (see Example 6).
- arrows
A vector of strings, one for each topic, indicating the nature of
the arrows that may be drawn at the ends of task bars. The individual values
may be "left"
, "right"
, "both"
or "neither"
.
Set arrows=NULL
, the default, to avoid such arrows.
- main
character string to be used as chart title.
- line.main
line where title occurs. If NA
, then the
title is placed in a default location; otherwise, it is line.main
lines above the top of the plot.
- cex.main
numeric, font-size factor for title.
- mgp
setting for par(mgp)
, within-axis spacing. The
default value tightens axis spacing.
- maiAdd
inches to add to the auto-computed margins at the bottom,
left, top, and right margins. The values may be negative (to tighten
margins) but the sum will be truncated to remain positive.
- axes
logical, TRUE
to draw the x axis. (Setting to
FALSE
permits detailed axis tweaking.)
- debug
logical value, TRUE
to monitor the work.
- ...
extra things handed down.
