     Hi Michael: 

     I tried to simplify the code, but still failed. 

              con <- url("http://quote.yahoo.com") 
              if(!inherits(try(open(con), silent = TRUE), "try-error")) 
             { 
                 close(con)                       

                 x <- get.hist.quote(instrument = "ibm", quote = c("Cl", "Vol")) 
                 plot(x, main = "International Business Machines Corp") 
             }

     It says: 
                Warning message: 
                 In open.connection(con) : too many redirects, aborting ...

      The more, it doesn't accept " library(quantmod)" and says: 

                 Error in library(quantmod) : there is no package called 'quantmod'

      Please help me!
