It's certainly possible to "rotate" abstract s
See my answer at Stack Overflow -- repeated here for anyone else who wants a
trivial function.
# coordinate transform: cartesian plane rotation
xyrot<-function(pairs,ang){
# pairs must be Nx2 matrix w/ x in first column and y in second
xrot <- pairs[,1]*cos(ang) - pairs[,2]*sin(ang)

Dear list,
Consider these two parallel segments in a plot.
plot(c(1, 6), c(2, 2), type="n", xlim=c(0, 7), ylim=c(-2, 6))
segments(1, 1, 6, 1)
segments(1, 3, 6, 3)
How can I rotate the two lines together by a defined angle?
Base graphics do not

Thank you all in advance.
