HOLA a TODOS.
tengo la siguiente tabla de datos como ejemplo:
FECHAHORA minutos Pp. temperatura
2-2-2014 00:10 1 13
2-2-2014 00:20 1 13,5
2-2-2014 00:30 1 13,4
tengo los datos cada diez minutos.
La idea es obtener: promedio DIARIO por intervalos, es
I have something which has been bugging me and I have even asked this on
cross validated but I did not get a response. Let's construct a simple
example. Below is the code.
A<-gl(2,4) #factor of 2 levels
B<-gl(4,2) #factor of 4 levels
df<-data.frame(y,A,B)
As you can see, B is nested within A.
