C2l,c2f and c2r

I know how to do c2l, c2f what is c2r. They are all in the same pattern hat/


Welcome to the forum!
Usually both C2R and C2b produce right leaning mini-cables or twists and C2L and C2f produce left leaning cables or twists. There are variations is how the sts are made but the idea of knitting sts out of order is the same.
Does you pattern define the stitches somewhere at the beginning or at the very end of the pattern or chart? Can you give us a link to the pattern or a pattern name?
