search for: x309

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! -- Ricardo Rodr?guez Your XEN ICT Team
