Dear R users

Are any R users aware of implementations of Semi-Definite optimization 
in R. 
For example, has anybody implemented any of the numerous public domain C 
libraries  for SDP in R and would they be willing to share.
My objective here is to implement variants of "Maximum Variance 
Unfolding" as outlined in, for example,  

Any ideas would be warmly appreciated.
