* Mean
The mean of the dataset is computed in R with the =mean= function:

#+Begin_src R :session *R* :exports both :results output
mean(data)
#+End_src

#+RESULTS:
: [1] 14.113

* Minimum and maximum
The minimum is computed using =min=, and the maximum with =max=.

#+Begin_src R :session *R* :exports both :results output
min(data)
max(data)
#+End_src

#+RESULTS:
: [1] 2.8
: [1] 23.4

* Median and standard deviation
The median is computed with =median=:

#+Begin_src R :session *R* :exports both :results output
median(data)
#+End_src

#+RESULTS:
: [1] 14.5

The standard deviation is computed with =sd=:

#+Begin_src R :session *R* :exports both :results output
sd(data)
#+End_src

#+RESULTS:
: [1] 4.334094
