[R] Manual sort in a for loop

I assume you need to use 'get' to retrieve the value:

table_year=1951
for (i in (paste("arunoff_",year,"_temp",sep=""))) {
         assign(paste("arunoff_",table_year,
sep=""),get(paste("arunoff_",table_year,"_temp"))[c(10,7,9,5,4,12,1,3,2,8,11,6),])
         table_year = table_year+1
         }

I have been able to carry out each re-arrangement without the use of the 'for' loop, but cannot seem to successfully execute the statements when incorporated into the loop. The code I have is as follows:
