Dear all,
I am using a program that generates similarity matrices in the following
non-redundant pairwise format.

a  b  0.4
a  c  0.5
a  d  0.3
b  c  0.9
b  d  0.6
c  d  0.2

matrix(c('a','a','a','b','b','c','b','c','d','c','d','d',.4,.5,.3,.9,.6,.2),byrow=F,nrow=6)

I would like to convert this to a full similarity matrix of the following
format.

      a      b     c     d
a    1     .4    .5    .3
b    .4     1    .9    .6
c    .5    .9     1    .2
d    .3    .6    .2     1

Additionally, I need to be able to apply this conversion to many data sets
with a different dimensions, so a generalized approach would be preferred.

Thanks for any advice, I'm stuck!
Lex
