Please, look at this...

 > substringJalapa <- regexpr("Jalapa", as.character(conagua$unidad ) ) 
!= -1
Hubo 50 o  más avisos (use warnings() para ver los primeros 50)
 > warnings()
Warning messages:
1: In regexpr("Jalapa", as.character(conagua$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...

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

Please, could you help me with this? Thanks!

Best,

Ricardo
