title.name doesn't work in netVisual_circle

[huipan1973]

It was working before. Now it doesn't show the title. Probably it is because of the update of dependent packages.

netVisual_circle(cellchat@net$count, vertex.weight = groupSize, weight.scale = TRUE, label.edge= FALSE, title.name = "Number of interactions")

The plot doesn't show "umber of interactions".

Hi @huipan1973

When netVisual_circle builds the plot object, title.name was appended after plot() event has happened. When actually showing the figure, plotting is clipped to the plot region (default is par(xpd = FALSE)), hence title is clipped out.

We need to explicitly set par(xpd = TRUE) so that plotting is clipped to the figure region (i.e. that also includes title).

par(xpd = TRUE)
netVisual_circle(cellchat@net$count, vertex.weight = groupSize, weight.scale = TRUE, label.edge = FALSE, 
                 title.name = "Number of interactions")
