Hello list members,
I would like to plot a timeSeries as a line, and superimpose events as points.
# series
x <- 1:100
x.ts <- timeSeries(x, x)
# events
y <- seq(10, 100, by = 10)
y.ts <- timeSeries(y, y)
# ok as individual plots
plot(x.ts, plot.args=list(type="l"))
plot(y.ts, plot.args=list(type="p"))
# also ok if both are plotted as points
plot(x.ts, y.ts, plot.args=list(type="p"), merge.args=(list(pos="union")))
# but the following plots both as lines
plot(x.ts, y.ts, plot.args=list(type="lp"), merge.args=(list(pos="union")))
the second character, "p", of type is ignored
I have also tried
plot(x.ts, plot.args=list(type="l"))
ts.points(y.ts)
Problem in points.raw.Internal(x = structure(.Data = c(1., 2., 3., 4., 5., 6.,
7., 8., ..: can't interpret class "timeSeries" as an S Version 2 vector
and
plot(x.ts, plot.args=list(type="l"))
tspoints(y.ts)
Problem: can't interpret class "timeSeries" as an S Version 2 vector
Any suggestions would be appreciated.
