Hello, 

I am a graduate student working to re-vamp my lab's proteomic analyses.  To start, I am simply working through many of the bioconductor package vignettes.  Pbase specifically applies to my goals, but I cannot complete the vignette with the data provided.  Perhaps I am accessing an outdated version?

When I first load the p dataset, I am missing some information.  I would appreciate being pointed in the right direction or towards the full data set so that I can proceed teaching myself this package!

From my console:

> library("Pbase")
> data(p)
> p
S4 class type     : Proteins
Class version     : 0.1
Created           : Wed Jul 16 02:58:33 2014
Number of Proteins: 9
Sequences:
  [1] A4UGR9 [2] A6H8Y1 ... [8] P04075-2 [9] P60709
Sequence features:
  [1] DB [2] AccessionNumber ... [10] Comment [11] Filename
Peptide features:
  [1] DB [2] AccessionNumber ... [46] spectrumFile [47] databaseFile

 

Specifically, highlighted, you'll see where my data set falls short.  Sequence features should go to [13] and should include "npeps" and "ENST".  Peptide features should only have [28] categories, where you can see my list has 47.

 

thanks for the input!

Indeed it seems you are using an old version of `Pbase`. What does `sessionInfo()` say? Did you try to update `Pbase` using `source("http://bioconductor.org/biocLite.R"); biocLite("Pbase")`?

thanks so much! that solved the problem.

These websites are great for the silly questions to get me over this initial learning hump for working in R.

If you have a second, could you tell me what it was that let you know I was using an old version?

First, I am one of the maintainers and that's why I am knowing that we changed the `p` object in the past sometimes. Next there is a line `Created` in the output with an outdated date: `Created : Wed Jul 16 02:58:33 2014`.
