[R] Graph in R with edge weights
Can you please show code example, how to draw graph with some nodes and edges, but with weights. I only found here http://www.bioconductor.org/packages/release/bioc/vignettes/Rgraphviz/inst/doc/Rgraphviz.pdf- Using edge weights for labels, but... Here an example: library(graph); library(Rgraphviz) myNodes = c(s, p, q, r) myEdges = list( s = list(edges = c(p, q)), p = list(edges = c(p, q)), q = list(edges = c(p, r)), r = list(edges = c(s))) g = new(graphNEL, nodes = myNodes, edgeL = myEdges, edgemode = directed) plot(g) but how about weights?

[R] Working with necessary columns in R (CSV)
Hi all. It will be great if some one will help me to solve my home task. So, the deal : i have .pcap file, i convert it to csv using tcpdump (tcpdump -tt -n -r x.pcap x.csv) CSV file looks like that : 12890084,761659 IP 10.10.20.20.47808 10.10.20.255.47808: UDP, length 12 12890084,761659 IP 10.10.20.20.47808 10.10.20.255.47808: TCP, length 12 12890084,761659 IP 10.10.20.20.47808 10.10.20.255.47808: HTML, length 12 ... 10 rows. Now, i need to open csv in R, and solve 5 problems, but i need to work only with UDP packets (not TCP,HTMP...). For example i need to count how many UDP packets are there, max and min time in UDP and so on. I see only two answers.. i need to scan (but how?) for UDP or i need to separate this csv, cut only needed rows, and work with them. Please help.
