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 ==.

You want

        ?regexpr

Something like

        regexpr("Jalapa", as.character( unidad ) ) != -1

HTH,

Chuck

Thanks!
