polygon angle option perpendicular to axis
I am trying to use the angle option in polygon to create polygons filled with horizontal and vertical lines. The polygons I am crating are irregular and it the angle function appears to set the angle of the shading perpendicular to the polygon sides rather than perpendicular to the axes. Is there any way to set the angle re...

Request - adding recycled "lwd" parameter to polygon
...tter: I would like to use a command like this: plot(c(1,8), 1:2, type="n") polygon(1:7, c(2,1,2,NA,2,1,2), col=c("red", "blue"), # border=c("green", "yellow"), border=c(1,10), lwd=c(1:10)) To create two triangles, with different line widths. But the polygon command doesn't seem to recycle the "lwd" parameter as it does for the col, lty, and the border parameters. I would like the resulting plot to look like what the following code will produce: plot(c(1,8), 1:2, type="n") polyg...

pie initial angle
Dear all, I'd like to produce a simple pie chart for a customer (I know it's bad but they insist), and I have some difficulties setting the initial angle. For example: pie(c(60, 40), init.angle=14) and pie(c(80, 20), init.angle=338) both present the slices in the same direction, where: pie(c(60, 40)) pie(c(80, 20)) present the slices in different directions. I read everything I could about init.angle argument, I even played with various fo...

polygon angle option perpendicular to axis
The angle is not based on the polygon edges, but it can seem that way if you do not use the asp=1 argument in your plot. Try this example, > plot(1:10, 1:10, type='n') > x <- c(1, 3, 5, 3) > y <- c(3, 5, 3, 1) > polygon(x, y, angle=0, density=10) > polygon(x, y + 4.5, angle=45,...

legend - bug with argument angle (PR#1404)
When legend() is used with the angle argument as follows, not only the boxes beside the legend text, but also the whole legend box is filled with shading lines.
