Dear Experts, I generated the plot attached. Every other thing is OK except the black horizontal lines which should appear like points or dots as the coloured ones. I can't understand why.
I tried to change it to look like dots by calling empty plots so that I will add them as points. Since I have a range of date that can fall any where within 2005, I tried: plot(1, type="n", xlab="", ylab="", xlim=c(as.Date("2005-01-01"),as.Date("2005-12-31")), ylim=c(-.5, -10)) ylim worked fine but xlim instead of appearing like date as indicated on the x-axes of the attached plot, translated to ordinary numbers (12800, 12900,13000, 13100). All the data is of the same format: 2005-01-04 -2.76105935648091 2005-01-19 -9.60813496025994 2005-01-22 -7.92101965866777 2005-02-19 -1.61308152604905 2005-02-24 -1.51497015807712 2005-05-09 -2.06465797304654 2005-05-11 -1.14840389007051 2005-05-16 -3.85281900888504 2005-06-13 -1.18659683796617 2005-06-17 -3.48787712566258 2005-06-22 -1.14223758296308 2005-07-18 -4.96013018907366 2005-08-03 -1.24313324914368 2005-08-07 -2.96672894841722 2005-08-10 -1.11868063781156 2005-08-25 -1.46453734930983 2005-09-13 -8.00895215754776 2005-09-15 -6.63439065989452 2005-10-13 -2.25054996925846 2005-12-15 -1.08933890547705 Thank you so much for your input.
