Subject: How to get the descriptive statistic of the whole dataframe?
In-Reply-To: <CANDXbipxaez_E1t2yrQMzg60CebcvOqZAn_+JCsrD8DHie2whQ@mail.gmail.com>
look into the *apply series of functions. In your case
apply(name.of.your.data.frame,2,min)
or
apply(name.of.your.data.frame,2,max)
will do. You can also put any summary function to your liking instead of
min/max.
Best,
Daniel
