Hi,
I have a basic question about aligning date labels for the x-axis
in an xyplot so that they align with the grid lines
from the panel.grid argument.
For example, with
x <- data.frame(
date = seq(as.Date("2005/01/01"), as.Date("2006/06/01"),
length.out = 20), value = runif(20))
xyplot(value ~ date, data = x,
panel = function(x, y, subscripts, ...)
{ panel.grid(h = -1, v = -1, col = "grey", lwd = 1, lty = 1)
panel.xyplot(x, y, ...)
})
How can I get the labels on the x-axis to align
with the vertical grid lines?
i.e. I have 6 vertical grid lines by default (v = -1)
in this example so I would like 6 labels along the x-axis
at the same points, whereas I see only 2 (2005 and 2006).
As an alternative I would be happy to just specify the number of labels
as long as panel.grid's vertical lines aligned with the labels.
