netVisual_heatmap for certain pathways on merged object

[JaneChik]

Hi! Thank you for the opportunity to compare different datasets. However, I've noticed that function netVisual_heatmap works fine on the whole merged cellchat object but crashes when user specifies particular pathways:

cellchat <- mergeCellChat(cellchat_list, add.names = names(cellchat_list))
pathways.show <- "WNT
netVisual_heatmap(cellchat, 
                  signaling = pathways.show,
                  cluster.cols = T, cluster.rows = T,
                  remove.isolate = T,
                  comparison = c(1,2), measure = "count",
                  title.name = paste(pathways.show, "signaling"))

There is no error but the resulting heatmap is empty.
It would be wonderful if you could add such option for merged objects!

Thanks!

@JaneChik The current function indeed does not support the input of signaling for merged objects. To use both measure and signaling, we need to modify the codes. Will do it later.

@sqjin Thank you! It will be very useful!
