A flexible Gantt Chart.

ganttChart(
  df,
  task_order = TRUE,
  mstone_add = task_order,
  mstone_spacing = 1,
  mstone_lwd = 2,
  axes = TRUE,
  mstone_font = 2,
  lighten_done = 0
)

Arguments

df	a data.frame (see details).
task_order	a logical. Should the tasks be ordered? See below for more details.
mstone_add	Should milestones be added?
mstone_spacing	spacing between milestones (expressed as figure unit).
mstone_lwd	lines width for the milestone.
axes	a logical. Should the axes be added?
mstone_font	font of milestone (ignore of axes is FALSE).
