I am using the KEGGgraph package to plot pathways with moderate success. When I am working with ~100 nodes, the gene names are included on my final plot. However, when I have larger datasets (~300 nodes) the names disappear. I am using the same method to obtain gene names and the same parameters to add them to the plots. Does anyone know how to solve this?

##Plot parameters
nA <- makeNodeAttrs(mapkG,label = nodesNames,fillcolor = col$To, fixedsize = TRUE, width = 10, height= 10, font = 20)
plot(mapkG, "dot", nodeAttrs = nA, edge=list(arrowsize="0.7"))
