using getSymbols() with variable symbols

I am trying to extract symbols and plot them in a loop, using a variable to assign each symbol, as follows:

symbol.list <- c("LSCC","LSI","LSTR","LTBR","LTON","LTRE","LTRX","LTXC")
for(i in 1:8){
     symbol <- getSymbols(symbol.list[i])
     ticker <- last(symbol,'12 months')
     barChart(ticker)
}
I am getting an error message "Error in NROW(x) - n : non-numeric argument to binary operator". I think I know where the problem is, but do not know how to extract the output of getSymbols() in a format than can be passed on to last(). Any help is appreciated.

Read ?getSymbols and run the examples.  Pay special attention to the
auto.assign arg.

Best,

This works (use auto.assign=FALSE in getSymbols)

require(quantmod)
symbol.list <- c("LSCC","LSI","LSTR","LTBR","LTON","LTRE","LTRX","LTXC")
 for(i in 1:8){#i=1
      symbol <- getSymbols(symbol.list[i],auto.assign=FALSE)
      ticker <- last(symbol,'12 months')
      barChart(ticker)
}
