Identifying Package for Function
While reading ?subset I'm referred to learn about dropvalues() as a
following operation. Yet, when I issue ?dropvalue I see, "No documentation
for '?dropvalues' in specified packages and libraries:".
How do I identify the library/package that contains a specific function
such as, in this case, dropvalues()?

looking for a string
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
