with.igraph.vs.R

# Allow for V(g) %$% color or g %>% V %$% color
# 
# Since %$% uses the generic `with` method, it is possible to tweek this to 
# deal with special cases like this. I know little about igraph, but this 
# may work.
# 
with.igraph.vs <- function(data, expr, ...) {
  eval(substitute(data$c, list(c = substitute(expr))))
}

# Example
library(magrittr)
library(igraph)
g <- erdos.renyi.game(100, 2/100)
V(g)$color <- "green"
g %>% V %$% color

I don't think this will work in general, e.g. for things like

V(g)[subset] $ color <- "red"

I also really don't know what's wrong with writing V(g)$color.
