Howto compile chemometrics package from source

Dear Jose,

First of all let me explain why your first approach did not work:

install.packages(chemometrics)
Erro em install.packages(chemometrics) :
  objeto 'chemometrics' n?o encontrado

R does not know an object named "chemometrics" and therefore complains. You 
should have typed

install.packages("chemometrics")

Note the quotes around the name of the package.

I just tried this in my Ubuntu machine and it worked as expected without the 
need of manually downloading anything. Of course the r-base-dev package needs 
to be installed as you already know.

Kind regards,

Johannes
