Dear R Users, 


Please I have the following query. I want to label  one of the axes of my graph with the follwing latex expression- \beta^{\prime}x, i.e I have the transpose of beta. How do I go abt this.

My second query is similar but it has to do with the conditioning symbol. The other axis is to be labelled as Y|X + \beta^{\prime}x. 


Thank you very much as I await assistance on this.

John
