## [igraph] alternative degree distribution

 From: Simone Gabbriellini Subject: [igraph] alternative degree distribution Date: Sun, 20 Feb 2011 13:24:38 +0100

```Hello List,

I have a vector of degrees, like:

part=c(1034, 981, 842, 523, 520, 506, 403, 345, 310, 299, 290, 284, 269, 218,
209, 204, 193, 175, 169, 110, 101, 95, 90, 87, 80, 78, 75, 72, 70, 66, 66, 61,
54, 54, 46, 45, 44, 43, 42, 40, 39, 37, 35, 35, 35, 34, 34, 32, 29, 28, 27, 26,
25, 25, 24, 21, 21, 20, 19, 18, 18, 18, 18, 16, 16, 16, 16, 14, 14, 14, 13, 13,
12, 12, 11, 11, 10, 9, 9, 9, 9, 8, 8, 8, 7, 7, 7, 7, 7, 7, 7, 7, 7, 6, 6, 6, 6,
6, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 4, 4, 4, 4, 4, 4, 4, 4, 3, 3, 3, 3,
3, 3, 3, 3, 3, 3, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 1, 1,
1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)

I am calculating its distribution like:

d<-table(part)
dd<-as.numeric(d)/sum(as.numeric(d))

and then I plot the result in log scale, trying to fit it with power.law.fit

I have a question regarding the plot. In the x scale, the largest value is
something like 60, which is the length of table(part), but it would be more
meaningful with the actual degree values, so I can read the plot like, for
example, "the probability of a node with degree 1034 is 0.005..."

Is there a way to force the plot use the dimnames(d) list?

best,
Simone
