Hi there, I am doing some network analysis working with k-cliques and over time I want to see what nodes are members of what cliques and how big these cliques are. I have managed to produce a matrix which shows which k-cliques each node is part of over the 100 time periods (slow though) but I cannot seem to calculate the size of each k-clique which is actually just a count.
Basically I have a dataframe like this with V1 being the node ID's and V2-V4 showing which k-cliques the nodes are part of : df <- as.data.frame(cbind(c(1,2,3,4,5,6,7,8),c(1,1,1,1,2,2,2,2),c(0,0,0,2,0,0,0,0),c(0,0,0,0,0,0,0,0))) # What I want is a dataframe like this where each k-clique value is replaced by its size: wanted <- as.data.frame(cbind(c(1,2,3,4,5,6,7,8),c(4,4,4,4,5,5,5,5),c(0,0,0,5,0,0,0,0),c(0,0,0,0,0,0,0,0))) It seems simple but I cannot get it working since these dataframes grow for each time period and the k-cliques change. I have tried using a loop that references to a table of the values but it does not work. I am sure there is an easy way, however. Hope to get some help, Kind regards, Frederik [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
