Need help to split a given matrix is a "sequential" way
...[5,] 200 50 180
[,1] [,2] [,3]
[1,] 100 180 80
[2,] 100 150 60
[3,] 100 50 60
[4,] 100 100 100
[5,] 100 50 120
Now each of dat1 and dat2 needs to be splited according to the it's 2nd
column i.e.
> dat11 <- dat1[which(dat1[,2] == unique(dat1[,2])[1]),]
> dat12 <- dat1[which(dat1[,2] == unique(dat1[,2])[2]),]
> dat13 <- dat1[which(dat1[,2] == unique(dat1[,2])[3]),]; dat11; dat12;
> dat13
[1] 200 100 80
[,1] [,2] [,3]
[1,] 200 150 180
[2,] 200 150 100
[,1] [,2] [,3]
[1,] 200 50 140
[2,] 200 50 180
similarly for dat2......

Como calcular la media de una gran cantidad de flow.frame en un ciclo "for" ...
...unda columna tiene el mismo
valor para las 10.000 filas en cada archivo asi es que sabemos el promedio
de antemano, pero quiero incluirlo en el calculo de todos modos. Para
calcular las medias he creado el siguiente nano-algoritmo que incluye un
ciclo "for" :
lista <- ls(pattern="dat12") # para usar solo los archivos que son del
mes 12 que son alrededor de 100
medias <- c(1:length(lista))
for (i in length(lista)){
medias[i] <- mean(exprs(lista[i][,5]))
}
pero obtengo el siguiente error:
Error in exprs(lista[i][, 5]) :
error in evaluating the argument ''o...
