There are certain pre-packaged commands in statnet and igraph that allows you to calculate various node-level measures. The statnet package seems to have a more comprehensive list, though igraph has a couple of measures that statnet does not have. The biggest problems (for my purposes) are that igraph does not have a command for calculating information centrality, and neither package seems to have commands for reach or distance-weighted reach. The latter two are pretty straight-forward, so I am posting functions that will let you easily calculate those two measures.
Here is a list of commands for node-level calculations included in the two packages. To find out what algorithms they use and how to use the commands, just look at the documentation with the help command for each index (?degree for example).
Reach and Distance-weighted Reach
Reach: 2-reach and 3-reach is simply the proportion of nodes you can reach within 2 steps or 3 steps, respectively. Here are codes for calculating this in igraph:
**Update 3/17/2015: I had forgotten to update these codes after igraph v0.6 updates. These should be now fixed.2-reach:
