[R] Matrix for correlation

2011-11-29 Thread Geophagus
hi @ all, I have problem with creating a matrix for a cor() function. I try to use the cor() function on a matrix to test the correlation between each value in a column. Maybe like corr(x, method = xyz). My x has two columns maybe like this: MEDIA VALUE Car 23 Train26 Plane 25 Cab

I'm not sure how you mean to calculate correlation if you have a single observation of each mediumcan you provide your data (or a subset thereof) so we can see what you are actually working with and if correlation makes sense. Michael On Tue, Nov 29, 2011 at 10:41 AM, Geophagus

Hi Michael, thank you so much for your fast reply. On the image below there is an example of what I mean. I need the correlation between the values on the fields with ?. http://r.789695.n4.nabble.com/file/n4119734/corr_ex.png But my source data is not in a matrix. It looks like the table in

I think everyone is worried about your data, not what a correlation matrix is. Now I think you may be even more turned around: you want a correlation between the values of the correlation matrix? Just dput() your data object and copy it into your email and we'll see if it's possible to calculate

Hi @ all and sorry for the confusion, my problem is solved. I also know a corellation is - it was only a formatting and describing problem. Grant gave me the right advice with the kruskal-wallis! Thanks GeOphagus -- View this message in context:
