How to make a network plot using a "from-to-dataframe"?-CodePudding

I have a data frame with two columns. The first column indicates from where someone comes and the second column includes where someone goes. Like in this example: Someone comes from "a" and goes to "a", "b" or "c". Is there a way in R to plot the network that results of this data using the following data frame? Or has the data frame be transformed further to be able to plot it?

from = c("a")
to = rep(c("a","b","c"),times=c(2,3,5))
data=cbind(from,to)

Thanks in advance.

You can plot this using the igraph package like so:

library(igraph)
graph <- graph_from_edgelist(data)
plot(graph)

You can use the chord diagram as well. Sample data:

from = c("a")
to = rep(c("a","b","c"),times=c(2,3,5))
data=cbind(from,to)

Sample code:

library(circlize)

  cols <- hcl.colors(4, "Temps")    

chordDiagram(data,
         col = cols,
         transparency = 0.1,
         link.lwd = 1,    # Line width
         link.lty = 1,    # Line type
         link.border = 1) # Border color

circos.clear()
