Issue when calling cnetplot on compareClusterResult with node_label set to "none"

[jimrperkins]

According to function documentation, the node_label argument can be either set to "category", "group", "all" or "none".

However, when calling cnetplot on compareClusterResult with node_label set to "none" I get an error:

library(clusterProfiler)
library(enrichplot)
data(gcSample)
xx <- compareCluster(gcSample, fun="enrichKEGG", organism="hsa", pvalueCutoff=0.05)
x2 <- pairwise_termsim(xx)
cnetplot(x2, node_label='none')

Error:

Error in str2lang(paste("foldChange", node_label)) : 
  <text>:1:12: unexpected symbol
1: foldChange none
               ^

I don't get an error when setting node_lable to "all".

Thanks!
Jim
