Hi all:
I have a question on how to go about creating a correlation matrix. I have a huge amount of data....21 variables for 3471 times. I want to see how each of the variables correlate to each other. Any help would be appreciated, including which package and which functions I should use to do this.
Hello,
that is not that huge and what is wrong with ?cor
A <- matrix(rnorm(21*3471),ncol=21) #you should replace A by your data matcor <- cor(A) #that is your correlation matrix image(matcor) # and how to watch it heatmap(matcor) # an other way to watch it
Hope this helps. Romain
