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()
).
This exercise is part of the course
Importing and Managing Financial Data in R
Exercise instructions
- 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.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Create BRK.A object
# Create col_names object from the colnames() of BRK.A
col_names <-
# Convert col_names into syntactically valid names
colnames(BRK.A) <-
