R: Gephi: manipulating dataframe to use with write.gexf

Question

I am trying to manipulate a data frame. As an example: say I have a dataframe containing customers and the shops they visit:

df = data.frame(customers = c(\"         


        

Answer 1

Please take a look to the function edge.list of rgexf(http://www.inside-r.org/packages/cran/rgexf/docs/edge.list). Using your example it would be something like this

library(rgexf)

# Your data
df = data.frame(customers = c("a", "b", "b", "c", "c"),
                shop_visited = c("X", "X", "Y", "X", "Z"))

# Getting nodes and edges
df2 <- edge.list(df)

Looks like this

> df2
$nodes
  id label
1  1     1
2  2     2
3  3     3

$edges
     [,1] [,2]
[1,]    1    1
[2,]    2    1
[3,]    2    2
[4,]    3    1
[5,]    3    3

Finally, you can use this to write a GEXF graph

# Building the graph
write.gexf(nodes=df2$nodes, edges=df2$edges)
