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()
).

Instruções do exercício
- Use
getSymbols()
and itsauto.assign
argument to create an object namedBRK.A
containing data for "BRK-A". - Use
colnames()
to create an object namedcol_names
that contains the column names for theBRK.A
object. - Use
make.names()
to convertcol_names
to syntactically valid names.
