It would be great to get a detailed question.
As far as I understood you wanted to plot your series in a single frame.
There are plenty examples in the help of plot.ts and plot.zoo for that.
I prefer working with time series be using the zoo package. But most things
can also be done within ts.

Hi,
R uses \ as a metacharacter, so you need a non-intuitive number of \:
mystring - Man\\Woman
# \\ is a metacharacter and a \, so it's equivalent to \ in normal text
sub(, /, mystring)

With the right mental model, though, it can become intuitive. That is, keep in
