[R] Creating a scatterplot with sequential dates on x-axis?

[Joshua Wiley]

Hi Caitlin,

Here are a couple of options for you:

plot(x = seq(from = as.Date("2011-05-01"), to = as.Date("2011-05-30"),
by = "day"),
     y = cumsum(runif(30)))

## using a bit of a shortcut
plot(x = as.Date("2011-05-01") + 0:29,
     y = cumsum(runif(30)))

Does that do what you want?
