dates or
times function to
use as the abscissa of the plot.
ts.plot function.
Plot.times makes an irregular time series object out of
x and
y and
calls
ts.plot with that time series. It sorts them so that
x is
sorted, hence if
x is not originally sorted type="l" will connect
points in the sorted order, not in the original order.
# The following plots someone's pay vs payday.
payday <- dates(c("12/15/93", "12/31/93", "1/15/94", "1/31/94",
"2/15/94", "2/28/94"), format = c("m/d/y"))
pay <- runif(length(payday), 500, 600)
plot(payday, pay, type = "l")
# The points are connected by lines and the x axis has tick marks
# labeled "12/15/93", "12/29/93", ..., "02/23/94" (every 14 days).
