 But, if I have understood correctly:

Thank you very much. It works nicely.

Re: [R] Auto Data in the ISLR Package

2017-12-17 Thread Eric Berger 
Hi Peter,
I looked at the Auto data frame and tested before I sent my reply. The
entries in the "name" column are actually models, such as

> head(Auto$name)
[1] chevrolet chevelle malibu buick skylark 320 plymouth satellite
  amc rebel sst
[5] ford torino   ford galaxie 500

What you are suggesting won't work. I agree with your "bedford" example as
a problem, but given the size of the result set in this case (~73 rows)
it's easy to eyeball the results and see if they're ok.

Regards,
Eric

Re: [R] Auto Data in the ISLR Package

2017-12-17 Thread peter dalgaard 
That probably works in this case, but it would cause grief if another car make 
had "ford" somewhere inside its name e.g. "bedford". Safer general practice is 

Auto[Auto$name %in% c("ford", "toyota"),]

or similar using subset().
