Dante-R is a program for normalising mass spectroscopy data. It is downloaded as an executable installer from the pacific northwest national laboratory.

Note that this is not an R zip file that you have to manage from within R - this is an executable. The one tricky point with installation is making sure that R is in your path. In my case on Windows 7 the path was not amended to contain R and so I had to add it manually.

To do this I added the following:
;C:\Program Files (x86)\R\R-2.10.1\bin

You get to the path from the Control Panel.

Once the path is added the Danter-R installer will then install all of the required R packages - in particular GTK support.

Dante-R has been used for unlabelled mass-spec data where there are a large number of samples, in cases where there are fewer samples as in the case of processing labelled data the methods might not be robust [Private discussion with the author] and so this has to be checked.
