[R] ggplot - unwanted sorted X values

[ashz]

Hi,

I have this script:

dat <- data.frame(X = halistat$Date,Y1 = halistat$avg,Y2 = halistat$stdev)
ggplot(data = dat, aes(x = X, y = Y1, ymin = Y1 - Y2, ymax = Y1 + Y2)) +
  geom_point() + # points at the means
  geom_line() + # if you want lines between pints
  geom_errorbar() # error bars, Y1 - Y2 and Y1 + Y2


halistat$Date values:
29/1/10
21/2/10
30/3/10
30/4/10
30/5/10


In the resulted plot the X values are sorted, how can I cancel it?

Thanks.
