Given a finitely generated group Γ with finite generating set R, we introduce the notion of an R-directed Anosov representation. This is a weakening of the notion of Anosov representations. Our main theorem gives a procedure to construct R-directed Anosov representations using Fock-Goncharov positivity. As an application of our main theorem, we construct large families of primitive stable representations from a rank 2 free group to PGL(n,R), including non-discrete and non-faithful examples. This is a joint work with Ser Peow Tan and Tengren Zhang.
