[R] How to measure correlations in terms of distance and draw them on a 2-dimmentional plot?

[weijian21cn]

Hi,

Suppose I have n variables, X1, X2, ..., Xn and want to visualize the
pairwise correlations on a 2-dimmensional plot. In particular, I plan to
mark down n dots on a piece of paper and  dot i represents Xi, in a way such
that the highly correlated variables are placed closer; that is, shorter the
distance between two dots the higher the correlation are between two
corresponding variables. Do you guys know any R packages can draw such
plots?

Thank you very much in advance!
