[R] looking for a string

[[Ricardo Rodriguez] Your XEN ICT Team]

Hi all,

I have not been able to find an answer to what is a simple question:

conaguaMexicoSub <- subset(conagua, unidad == "Jalapa", select = 
c(equipo,X101:X309))

This subset gives me all the rows from conagua where unidad is Jalapa. 
But, please, how do I get all the rows where unidad contents Jalapa?

I've been looking at regex, but I didn't find how pass one to unidad ==.

Thanks!
