Re: [igraph] igraph doesn't recognise its shape="star"???

[Gábor Csárdi]

I don't think there is a built-in "star" shape. AFAIR there is one in the examples, so just take the code from there.

Dear all, 

I had a good R session when my (apple) computer crashed. Returning to what I was doing, igraph generated this very odd error:

 

Error in igraph.check.shapes(params("vertex", "shape")) : 

  Bad vertex shape(s): star. 

Since "star" is a good vertex shape, and the very same code worked and produced plots with stars before the crash, I figured the problem is with something in the environment that was there before and isn’t there now (after the crash). What could that be?And why doesn’t igraph works anymore as it used to?

I paste some code below, but I don’t think its relevant as the problem is with “star”, right?

Thanks,

Uri
