Hi all, I use following command to make getSymbols (from quantmod package) get data from locally stored csv files. setDefaults(getSymbols,src='csv') My problem is that if the data is not found locally, I want it to get it from yahoo/google. How to go about doing this. If setDefaults allowed multiple sources, it would have been possible. Something like the following: setDefaults(getSymbols,src='csv yahoo') Please let me know how this can be done.
Write your own getSymbols function, e.g. getSymbols.csv2yahoo. Then wrap your call to getSymbols.csv in a try or tryCatch call. If the getSymbols.csv call fails, you can then call getSymbols.yahoo.
Thanks.
