[R] Problem on plotting TS using GGPLOT

[Bogaso]

Let me be more specific. My goal is to plot following multiple TS, using
ggplot2

dat1 <- zooreg(matrix(rnorm(306), 51), as.yearmon(as.Date("2000-01-01")),
frequency=12)
colnames(dat1) <- letters[1:6]
dat1

Still I can not get what is problem in my ggplot2 codes. Please give some
idea.

Best,
