see ?dist
   
  there's an example
      
       x <- matrix(rnorm(100), nrow=5)
     m <- as.matrix(dist(x))
     d <- as.dist(m)

'as.dist' is what you're probably looking for

  Dear R-helpers,

i am a beginner of R and i am using cluster package to do hierarchical
clustering

i am wondering if i can use my own distance matrix to do the hierarchical
clustering without using dist() function.

if i have my own distance matrix, how can i ask hclust() function to recongnize
it( as the output of dist() function).

thank you very much and i looking forward to hearing from you.

Marshall
