Suppose I have the following
y <- rnorm(10) b <- as.factor(sample(1:4,10,replace=T)) qplot(1:10, y, shape=b)
How do I change the shapes that are used using ggplot2 ?

Be:
qplot(1:10, y, shape=b) + scale_shape_manual(value=c(0,5,6,15))
The shapes are the same> y <- rnorm(10) > b <- as.factor(sample(1:4,10,replace=T)) > qplot(1:10, y, shape=b.

Hi,
I put several shapes (like Ellipse and Rectangle) on a Canvas. Now, I want user to be able to drag & drop these shapes. Is there some predefined functionality that I can use, or I should implement the drag & drop myself using the mouse events ?
Thanks...

I'm working on an application, I need to be able to combine two overlapping arbitrary shapes as drawn by the user. This would be a Union operation on the two shapes. The resultant shape would be the silhouette of the two overlapping shapes.
The shapes...

Wind clockwise along the current shape to the next point and check to see if one or more new shape.
Call that Shape A and make it the current shape.
For you?
How about:
Pick the left-most point of the two shapes.

You don't paint shapes onto a Canvas if you're using Graphics and Graphics2D functions like drawRect, drawPolygon, drawOval, etc.
Is to have a List of your shapes (either one list for all or one for circles and one for lines.

If I draw any shape onto a surface (with SRCALPHA flag on) in a partially transparent colour it completely replaces what was underneath it, instead of overlapping like you would expect in image editors.
How can I make the shapes overlap properly?

p.s.
You could use blit with appropriate BLEND_* values (keeping the shapes as separate surfaces channel, draw your shape onto that surface, then blit with blending onto the final surface.
