Please, look at this...

!= -1
Hubo 50 o más avisos (use warnings() para ver los primeros 50)
> warnings()
Warning messages:
1: In regexpr("Jalapa", as.character(conagua$unidad)) ... :
string de entrada 1 es inválida en este locale
2: In regexpr("Jalapa", as.character(conagua$unidad)) ... :
string de entrada 2 es inválida en este locale
3: In regexpr("Jalapa", as.character(conagua$unidad)) ... :
string de entrada 3 es inválida en este locale
The error means something like "Input string 1 is not valid for this
locale". Sorry, I am not able yet to control messages language.
I don't know how to pass regexpr(.........) to my problem...
Like this:
conaguaMexicoSub <- subset(conagua,
regexpr("Jalapa", as.character( unidad ) ) != -1
select = c(equipo,X101:X309))
But it looks like you have to sort out some issues concerning dueling
locales first.

Please, could you help me with this? Thanks!
