R help - Aug 2014 - Calculation of network centrality measures weighted by network size

Hello,

My name is Jenny Jiang and I am a Finance Honours research student from the
University of New South Wales Australia. Currently my research project involves
the calculating of some network centrality measures in R, which are degree,
closeness, betweenness and eigen vector. However I am having some issue
regarding to the calculation of the weighted centrality measures by network
size. For example, currently my code allows me to calculate centrality measures
for each firm year, and now I would like to calculate centrality measures
weighted by the firm network size for each firm year. I have attached my current
R code and a data example for you in .txt format to have a look. If you could
provide me the R code regarding to how to do that that would be really helpful.

I cannot be more than appreciated.

Best regards

Jenny
