 Store in a list:

data = list()
 for(x  in 1:3){
   data[[vektor[x]]] = read.table(.......)

 then you can do data[["RA940101"]] to get that set of data.

 You can also do this by number:

 data[[x]] = read.table(....)

 and then get data[[1]], data[[2]] etc etc.

See any basic R help/tutorial for more information about 'lists'.
