Plotting a dataframe using igraph in R

Question

The first column in this dataframe represents the Twitter screenName. The second column contains the @mentions in the tweet. There could be more than one @mention in this column.

When I plot it I get the V1 nodes connected to a vector not each element in the yy1 vector

How can i show the connections between each node and each element?

You could try it like this

library(igraph)
library(data.table)
library(splitstackshape)
dt <- data.table(V1=c("from1", "from2", "from3"), 
                 yy1=c("@to1, @to2", "@to3, @to4", "@to5"))
dt <- cSplit(dt, 2, ", ", "long")[, yy1:=sub("@", "", yy1, fixed=T)]
dt %>% graph_from_data_frame %>% plot
