Hello,
I have a plotting function (plot_neighborhood) that is called by another function; it previously worked but currently does not. When I call this function from the command line, it works though. Below is the error message and the end of the trace. (in the example below, 'n' is an integer referring to vertex ID; it is supposed to plot the vertex and its neighborhood).
Error in lazy_dots(i = i, ..., .follow_symbols = TRUE) :
use of NULL environment is defunct

8: .Call(make_lazy_dots, environment(), .follow_symbols)
7: lazy_dots(i = i, ..., .follow_symbols = TRUE)
6: `[.igraph.vs`(V(g), n) at plot_neighborhood.R#15
5: V(g)[n] at plot_neighborhood.R#15
I have another very similar plotting function (also called from this 'helper' function) which works without issue. Any ideas?
Thanks,
Chris
