Hello, As recommended by N. Gunther, I'm writing you because I have some difficulties to create a script to track computer performance, as done in Holtman, 2005 (Visualization techniques for analysing patterns in system performance).
I would like to do a leveplot, with the kind of file here enclosed. I assume I should create a matrix in R, then use the function 'image'. As I am not familiar with the lattice package, I have some difficulties to move ahead : I think my pb is in the creation of the matrix. I am not able to create sthing consistent with the image function. I am even thinking I should build my input csv file differently, but I am not sure how to do... Is someone able to help me ? Thank you very much ! REgards, Michel ---------- Forwarded message ---------- From: Red Roo <redr...@yahoo.com> Date: Tue, Aug 24, 2010 at 3:46 PM Subject: Re: [R-sig-hpc] Holtman's levelplot ?

He is also an instructor for my "Guerrilla Data Analysis Techniques" class http://www.perfdynamics.com/Classes/Outlines/gdata.html and we just discussed this plot 2 weeks ago. --Neil Gunther Taking The Pith Out Of Performance http://perfdynamics.blogspot.com/ Follow me on Twitter http://twitter.com/DrQz Performance Dynamics Company http://www.perfdynamics.com/ >>> >> >>On 08/24/2010 03:47 AM, Michel Lutz wrote: >> >>Hello to all, >>> >>>I am sorry for disturbing you, but I really don't know where/who to ask... >>>so if this distribution list is not dealing with my concern, please excuse >>>me... >>> >>>Here is my concern : I am trying to do a levelplot as in Holtman, 2005 >>>(Visualization techniques for analysing patterns in system performance >>>data), to display CPU usage according to the day of the month (y) and >>>minutes (x). >>> >>>I am familiar with R basic features, but not at all with lattice package and >>>I don't understand the logic of this leveplot function, especially in the >>>particular case of a time series. >>> >>>I've read all the material found in the web, but I am completely stuck... >>> >>>Does someone have some clues or documentation that could help me to draw >>>such a plot ?
