Hello Jorge,
Sorry, my aim is to get each individual separately, so that if I input
> A1 # the the result would be
1
This because I would like to use
lm.D <- lm(y~A1+A1+A3...)
Thanks,
Diego

Hi Diego,
Try this:
z<-As["A1"]+As["A2"]; names(z)<-"z"
z
4
HTH,
Jorge

The problem is that A1, A2,... still unknown, so that I have the following error
> A1
object "A1" not found
Thank you in advance!

Hi Diego,
Is this what you want?
# Data set
set.seed(123)
x1<-paste("A", 1:6, sep = "")
x2<- round(rgamma(6,2,1))
x3<-paste("B", 1:6, sep = "")
x4<- round(rgamma(6,2,1))
data1 <- data.frame(x1,x2,x3,x4)
data1
x1 x2 x3 x4
1 A1 1 B1 0
2 A2 3 B2 0
3 A3 0 B3 3
4 A4 2 B4 2
5 A5 4 B5 2
6 A6 2 B6 2
# A's
As=as.numeric(t(data1[,1:2])[-1,])
names(As)=paste('A',1:length(As),sep="")
As
A1 A2 A3 A4 A5 A6
1 3 0 2 4 2
# B's
Bs=as.numeric(t(data1[,3:4])[-1,])
names(Bs)=paste('B',1:length(Bs),sep="")
Bs
B1 B2 B3 B4 B5 B6
0 0 3 2 2 2
HTH,
Jorge

I presume that 4, 2, 0 are the first few values of x2. In which case, I
think that what you want is simply this:
names(x2) <- x1
