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
