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'.
