[R] Problem on plotting TS using GGPLOT

[Bogaso]

Thanks for this reply. Here my goal is to plot multiple time series in the
same plotting window. Here y variable has 306 elements, however each value
is associated with factor which is represented by "vv" variable.

 I want to plot total 6 time series, for example 1st 51 values of y,
represented by "a" should be treated as single TS, with index as index of
"dat2".....................similarly 2nd 51 values of y, represented by "b"
should be treated as another single TS, with index as index of
"dat2"...........and so on.

What is the problem here?

Thanks,
