问题 From my dataset I'm trying to make pairs based on a ranking. my data looks like ID grp rank 1 grp1 1 1 grp2 1 1 grp3 2 2 grp1 1 2 grp2 2 2 grp2 2 2 grp2 2 2 grp3 2 2 grp1 3 The output I am aiming for is the following: for each ID if rank = 1 then grp in source and destination are the same = grp If rank is different from 1 then source = take grp from previous rank destination = take group from current rank If more then one group exist for the same ranking then an additional line needs to be

问题 I've created a graph from a dataframe with igraph that shows how students move between vocational courses. The first two columns are 'From' and 'To' which contain the qualification names (vertices) with an occurrence for each time a student enrols in a course for the first time (From) and then enrols in another (To). The remaining columns contain values relating to that particular student's demographics. I'd like to create and plot individual networks for movements 'To' OR 'From' each

问题 I'm creating ego networks from a graph in iGraph with R, as per the answer that was kindly provided to this question. I then want to export each ego network as a plot in a PDF or image file (preferably PDF). As there are 788 'ego networks' in the full dataframe I'd like to make the file name of the PDF match the relevant node ID for the network i.e. the 'From' column of the dataframe. Otherwise it's too hard to find the particular network that I want. How can this be done? Here's a sample of
