rmatrixvisualizationcorrelation

How can I create a correlation matrix in R?


I have 92 set of data of same type.

I want to make a correlation matrix for any two combinations possible.

i.e., I want a matrix of 92x92.

such that element (ci,cj) should be correlation between ci and cj.

How do I do that?


Solution

  • An example,

     d <- data.frame(x1=rnorm(10),
                     x2=rnorm(10),
                     x3=rnorm(10))
    cor(d) # get correlations (returns matrix)
