Hi I think I am probably being a complete idiot, but I can't change the fontsize in simple Rgraphviz plots: library("Rgraphviz") set.seed(123) V <- letters[1:10] M <- 1:4 g1 <- randomGraph(V, M, 0.2) plot(g1) plot(g1, attrs=list(node = list(fontsize="80"))) Both of these produce the same plot, with no change in fontsize. I'm probably using the attributes incorrectly, so please someone put me out of misery and show me! Please don't ask me to upgrade Rgraphviz - I need this version to work with my version of graphviz sessionInfo() R version 2.7.2 (2008-08-25) i386-pc-mingw32 locale: LC_COLLATE=English_United Kingdom.1252;LC_CTYPE=English_United Kingdom.1252;LC_MONETARY=English_United Kingdom.1252;LC_NUMERIC=C;LC_TIME=English_United Kingdom.1252 attached base packages: [1] tools stats graphics grDevices utils datasets methods base other attached packages: [1] Rgraphviz_1.16.0 topGO_1.8.1 SparseM_0.78 GO.db_2.2.0 AnnotationDbi_1.2.2 RSQLite_0.7-0 DBI_0.2-4 [8] Biobase_2.0.1 graph_1.18.1 RODBC_1.2-3 loaded via a namespace (and not attached): [1] cluster_1.11.11 Thanks Mick Head of Informatics Institute for Animal Health Compton Berks RG20 7NN 01635 578411 http://www.iah.ac.uk/research/bioinformatics/bioinf.shtml The information contained in this message may be confide...{{dropped:14}}
