Hello,
I apologise if someone has already answered this but I searched and
googled but didn't find anything.
I have a matrix which gives me the similarity of each item to each
other. I would like to turn this matrix into something like what they
have in the graph package with the nodes and edges.
http://cran.r-project.org/doc/packages/graph.pdf . However I cannot find
a method to convert my matrix to an object that graph can use.
my similarity matrix looks like:
> sim[1:4,]
a b c d
[a] 1.000000000 0.0223676 0.9723831 0.3943310
[b] 0.325141612 1.0000000 0.9644216 0.5460461
[c] 0.002109751 0.3426540 1.0000000 0.7080224
[d] 0.250153137 0.1987485 0.7391222 1.0000000
please don't get caught up with the numbers I simple made this to show.
I have not produce the code yet to make my similitary matrix.
Does anyone know a method to do this or do I have to write something. :(
If I do any starter code :D jj. If I've read something wrong or
misunderstood my apologies.
cheers,
Paul
