Hi There Many thnx for coming back to me & so quickly! Just to add to the plot: 1. I have R2.8.1 also fully loaded on this laptop, but did not bother to populate packages as R2.9.0 was out so quickly - and once loaded I tried to load Rgraphviz on R2.9.0 ~ to no avail 2. However, I have Rgraphviz running on my home laptop also on Windows XP on R2.8.1, and yesterday boldly copied all library files on Rgraphviz to my work laptop (Windows XP) now under R2.8.1 and voila it's running and also tested the R> example(layoutGraph) > example(layoutGraph) lytGrp> library(graph) lytGrp> set.seed(123) lytGrp> V <- letters[1:10] lytGrp> M <- 1:4 lytGrp> g1 <- randomGraph(V, M, 0.8) lytGrp> x <- layoutGraph(g1) lytGrp> library(graph) 3. No same luck on R2.9.0!

I have some ideas on how to fix this, but I need to brush up on my knowledge on exactly how DLLs are loaded, to see if it is possible to catch this at an earlier stage. Essentially, I need to fix this in the coming days (weeks). There has been (too many) emails on this in the last couple of days, so it has certainly been pushed up my priority schedule. Finally, I have no idea why you get the error when you load Rgraphviz. If you can successfully run R> example(layoutGraph) then everything should be working.

Hi Kasper, I can successfully run example(layoutGraph), so that's good. The Windows error box might be related to Graphviz itself - in the past there was some information on the www.graphviz.org about the error (don't remember if it was the same error as now, although it was the same error as I was having at the time), but it's gone now. Their suggested fix at the time didn't work either, so maybe that's why they removed it! I'm going to be doing some network analysis, so I'll probably be using Rgraphviz to make the network plots. Hopefully there will be no problems except for the irritating error box every time. Thanks for all your work on this!
