Dear all,

When one tries to load a non-installed package you get the error: 

Error in library(xyz) : there is no package called 'xyz'

I noticed on several occasions that this puzzles beginners. Therefore I suggest to change the error description in:

Error in library(xyz) : there is no package called 'xyz' installed on this machine. Check the name of the package or use install.packages("xyz") to install it.

Best regards,

Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
