I'm going to analyse (some exploratory analysis and I'm new to this subject) large networks in R. So I have a FLICKR data set in hand.

FLICKR DATA

If you see the data set, it consists of 4 different CSV file with different attribute of a graph or network. How to convert this data to igraph object?

I have see the following solution in the Stack overflow.

SOL 1, SOL 2

I also know there is a function called csv.to.igraph function in the influenceR package, but unable to serve my purpose.

Any kind of help is appreciated.

Your quenstion is (probably) too broad. It should focus on a single problem.

But here is a first approach, it reads the relevant csv (with edges), and creates a (directed) graph

library(data.table)
library(igraph)
edges <- data.table::fread("./data/Flickr-dataset/data/edges.csv")
g <- igraph::graph_from_data_frame(d = edges, directed = TRUE)
