[igraph] converting graph objects to data.frame

[Filippo Santi]

Dear all,

I am trying to convert an igraph object into a data.frame. As I am
interested in the vertex attributes (I need to extract some network
characteristics to be included into an econometric analysis), I do

*net.df <- as_data_frame(net, what = 'vertices')*

However, this does not work. It did work the first time I used the command,
but for some reasons now it returns the following error:

*Error in as.data.frame.default(value, stringsAsFactors = FALSE, ...) : *
* cannot coerce class ""igraph"" to a data.frame*

I had to replicate some analysis, but the only change I made concerned a
few more attributes that I computed to be extracted. Any suggestion?

Dear Gabor,

I am using the function as_data_frame, but it returns the error related to
as.data.frame.default(...) as I showed to you. I found it is in conflict
with a 'dplyr' package function as.data.frame, despite the different
spelling. I resorted imposing the :: operator to call the igraph's function.

Thank you again

Filippo

Use the following syntax:
net.df <- igraph::as_data_frame(...)
It should work!

Dear Claude, thank you very much. I eventually used the :: function
assignation and got the result. Best
