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
