Problems with the RunSlingshot() function

[leo971001]

It appears when I run the RunSlingshot() function using my own data:
1: No shared levels found between names(values) of the manual scale and the data's fill values.
2: No shared levels found between names(values) of the manual scale and the data's fill values.
and I can't get the figure.

when I use the data("pancreas_sub"), the same question arises here：
1: No shared levels found between names(values) of the manual scale and the data's fill values.
2: No shared levels found between names(values) of the manual scale and the data's fill values.

How do I fix this?

I had the same problem, did you solve it?

lineages_layers <- SCP::LineagePlot(srt.IC, lineages = c("Lineage1","dpt_pseudotime" ),return_layer = T)
lineages_layers <- lineages_layers[!names(lineages_layers) %in% c("lab_layer")]
gg <- SCP::CellDimPlot(srt.IC, group.by = "group.cellchat",pt.size = 3,
                       reduction = "UMAP",show_stat = T,palcolor = scPalette(3),
                       label = F, label_insitu = F)

pp <- gg+
  # scale_color_manual(values = scPalette(3))+
  guides(color = guide_legend(
    title = "Groups",
    override.aes = list(color=scPalette(3),size=4)))+
  ggnewscale::new_scale_colour()+lineages_layers

I can't get the figure, but solve the problem a lit bit.

My cellgroup number is 3，so I define my length=3 scPalette(3). To solve the plot problem, firstly, run LineagePlot to get lineages_layers, then run CellDimPlot to get cells plot. Then add them, use guides(color = guide_legend( title = "Groups", override.aes = list(color=scPalette(3),size=4)))+ to solve legend conflicts.

The problem may be caused by ggnewscale package.

Best wishes.
