Network Analysis (2) Practice Using igraph and Gephi
This video is for the Network Analysis and Visualization Workshop organized at the Virtual Annual Conference of Comparative and International Education Society 2020 (vCIES 2020) in April 2020.
There are two lecture videos for this workshop. The first video includes the theory part of my lecture and the second video file is for the practice of the igraph and Gephi with the data files.
This second session is for practice with analysis software, igraph in R and Gephi.
You can find and download the data files and R script from this GitHub address:
github.com/Arizonagong/vCIES2020_Network-Analysis
and the script and data files are in the "igraph" folder.

    Hi Sir... Its a good tutorial for the analysis of the Social Network. I am following the theory and the practical part. I have the following question which arise when you created Adjacency Matrix (undirected) at the video tutorial at 26:15 (you can find the scenario when the video is at 26: 15 sec) 1) The first column consists of the Student_ID. Does the first row consists of the Student_ID as well ? In Adjacncy matrix we only have node at the first column and the rest matrix consists of edges only. 2) why the adjacency matrix was symmetric i.e. I can understand no value at the diagonal but please define the same matrix above and below the diagonal element. 3) Sir I am not been able to get the Plotting (can not detect the clustering and community as the major of the area is covered with black color) as much clear and attractive as yours in the tutorial. Can you shed some light on this sir? kindly elaborate ASAP.

      답글 주셔서 감사드립니다. Bipartite network는 저도 개인적으로 매우 흥미로워하는 주제인데 별도의 강의는 저도 본적이 없네요. 제가 나중에 더 공부하면 강의 정리해서 한번 올려보겠습니다.

    Thanks for the video but I encountered some errors from the stage of creating an igraph object from the dataframes like below. Warning message: In igraph_opt("return.vs.es") : internal error -3 in R_decompress1 Do you know why? if so, any suggestion?

      @byoung-gyugong7007 3 года назад

      Thanks for your comment and interest. I haven’t seen any of the books for SNA with R programming. I rather recommend textbooks or tutorials addressing general network analysis with R such as ‘Statistical network analysis with igraoh’ by Gabor Csardi. You can freely download this tutorial book in the internet.
