[igraph] Can't control vertex.size when plotting over geographic map

[Elliot Meador]

Hello, 

I'm new to the igraph help-list, so please excuse any violations of norms.

For some reason, I cannot control the vertex size attribute when I plot an igraph object over a map. 

Specifically, I think the issue lies with the plot parameter: rescale = FALSE.

# Here is my code

par(mar = c(1,0,1,0))

plot(great_britian_boundary, col = 'grey', border = 'grey') #produces a base map

# edges 

E(g)$color <- 'black'

E(g)$arrow.size <- .25

E(g)$lty <- 2

E(g)$size <- 1.75

# vertices

V(g)$label <- NA

V(g)$color <- 'black'

V(g)$size <- 15 # setting vertex size, but does not show up in plot

plot(g, layout = g_locations, rescale = F,add = TRUE, # adds the igraph

     xlim = c(5512.999, 655644.8),

     ylim = c(5337.901, 1220301.5))#

This produces, this image

par(mar = c(1,0,1,0))

plot(great_britian_boundary, col = 'grey', border = 'grey')

# edges 

E(g)$color <- 'black'

E(g)$arrow.size <- .25

E(g)$lty <- 2

E(g)$size <- 1.75

# vertices

V(g)$label <- NA

V(g)$color <- 'black'

V(g)$size <- 15

plot(g, layout = g_locations, rescale = F,add = TRUE,

     xlim = c(5512.999, 655644.8),

     ylim = c(5337.901, 1220301.5))#

par(mar = c(1,0,1,0))

plot(great_britian_boundary, col = 'grey', border = 'grey')

# edges 

E(g)$color <- 'black'

E(g)$arrow.size <- .25

E(g)$lty <- 2

E(g)$size <- 1.75

# vertices

V(g)$label <- NA

V(g)$color <- 'black'

V(g)$size <- 15

plot(g, layout = g_locations, rescale = F,add = TRUE,

     xlim = c(5512.999, 655644.8),

     ylim = c(5337.901, 1220301.5))#

Is there somehow I can control the graph plot attributes in a similar way to when rescale is set to FALSE?

Thanks, 

Elliot
