Hi,
Having a matrix F(189,6575) I want to do this:
z1<-subset(F[,1], F[,1] >= 5 & F[,1] <= 10)
.
.
.
z189<-subset(F[,189], F[,189] >= 5 & F[,189] <= 10)
I would prefer to have an empty matrix, say 'z' in order to fill its
columns with the output of subsetting F. But each of the subsets can
differ in length. It's to say:
length(z1)
1189
length(z2)
1238
Don't know how to set up this with a for loop or the use of apply:
z<-189
for (i in 1:189)
{z[i]<-subset(F.zoo[,i], F.zoo[,i] >= 5 & z1 <= 10)}
Error in z[i] <- subset(F.zoo[, i], F.zoo[, i] >= 5 & z1 <= 10) :
nothing to replace with
or
z<-matrix(0,6575,189)
for (i in 1:189)
{z[i]<-subset(F.zoo[,i], F.zoo[,i] >= 5 & z1 <= 10)}
new error
Thanks,
Antonio
