Dear R users, I want to plot not only triangles point up and triangles point down, which is easy using the "pch" argument to "points". I want to plot left and right pointing triangles as well. They must be fillable with colour. I browsed a little in the documentation, tried rotating the up and down pointing triangles, but of no avail. Any suggestions will be appreciated.
