Plotting legend

[ebey]

currently the colors in the legend only match the corresponding nodes for numeric attributes.

how does plot.network translate a non-numeric attribute into a color?

[skyebend]

it uses network's (undocumented) as.color() function:
as.color
function (x)
{
if (is.numeric(x)) {
if (any(x != round(x), na.rm = TRUE)) {
return(gray((x - min(x))/(max(x) - min(x))))
}
else return(x)
}
if (is.factor(x)) {
return(match(levels(x)[x], levels(x)))
}
if (is.character(x)) {
if (all(is.color(x)))
return(x)
else {
return(match(x, sort(unique(x))))
}
}
}

which seems to be basically mapping each element (or factor level) to an integer value and then using the default palette

Thanks Skye!

The fill colors are fixed in commit cc4e503
