[R-SIG-Finance] ploting time series

[fernando]

Hi Mark,

An example would be the following code

x <- c("1jan1997", "2jan1997", "3jan1997", "4jan1997")
y <- c(-.3, 0.2, -0.2, 0.3)
date <- as.Date(x, "%d%b%Y")
plot(date,y, type="l", ylim=c(-0.32,0.32))
segments(1,-.2,4,-.2) # I want a segment from Thu through Sat at y = -0.2

Thanks in advance.

Cheers
