Dear Igraph develpppers and memebers
I am facing some difficulties to remove redundancy from a network using
'simplify' in 'igraph' package. My network is in a table file, firstly my
data frame as an object and secondly I run the command line: simplify(g,
remove.multiple = TRUE), and have an output error saying created object is
not an igraph object . My question is how I can convert a text file to
a graph object to avoid this error message ?
Here is my input and the output in R :
> g <- read.table("data.txt")
> g
V1 V2
1 a b
2 b a
3 d o
4 d l
> g <- read.table("data.txt")
> simplify(g, remove.multiple = TRUE)
Error in simplify(g, remove.multiple = TRUE) : Not a graph object
Thanks in advance
