Exercise

Create valid name for one instrument

If you are only downloading data for a single symbol and that symbol is not a syntactically valid name, you can set auto.assign = FALSE in your call to getSymbols(). That will allow you to directly assign the output to a syntactically valid name.

You may also want to convert the column names to syntactically valid names. That is a good idea if you plan to use the data in functions that expect column names to be syntactically valid names (e.g. lm()).

Instructions

100 XP
  • Use getSymbols() and its auto.assign argument to create an object named BRK.A containing data for "BRK-A".
  • Use colnames() to create an object named col_names that contains the column names for the BRK.A object.
  • Use make.names() to convert col_names to syntactically valid names.
