BUG | do_FeaturePlot | The legend titles are not displayed anymore

[frac2738]

It has been a while that do_FeaturePlot has a strange behaviour.
The legend title is not displayed anymore.

library(SCpubr)
options("SCpubr.ColorPaletteEnds" = TRUE)

exp_Integrated <- readRDS(...)
do_FeaturePlot(exp_Integrated, c("nFeature_RNA","nCount_RNA"), legend.position = "right", 
                            use_viridis = TRUE, viridis.palette = "D",viridis.direction = -1)

The code above returns a figure without the legend title

This make difficult to know which one is which.
Of course I know that the left is "nFeature_RNA" and the right is "nCount_RNA", but this can be problematic when the figures are shared.

So far a workaround is to add the title to the single plots and then combine them together

u1 <- do_FeaturePlot(exp_Integrated, "nFeature_RNA", use_viridis = TRUE, viridis.palette = "D",viridis.direction = -1) + ggtitle("nFeature")
u2 <- do_FeaturePlot(exp_Integrated, "nCount_RNA", use_viridis = TRUE, viridis.palette = "D",viridis.direction = -1)+ggtitle("nCount")
u1|u2

I tried to re-install SCpubr multiple times, but nothing has changed.
I don't think this is an intended behaviour...is that correct?

Hi @frac2738,

Thank you for bringing this up! Let me have a quick look and get back to you!

Hi @frac2738,

This seems to be an odd bug that somehow it is not showing up in my environment. I might need some time to further delve into it and see what is breaking on another environment that reproduces the bug.

Before that, could I ask you to quickly download the latest commit from GitHub and check again if legend titles are still missing?

devtools::install_github("enblacar/SCpubr", ref = "488c3aadd9876eb404cbdb80c844049fda67ca02")

Thanks a lot! Will keep you updated on this.

Hi @enblacar,
thanks for taking the time to looking into this bug.

I upgrade the version I had to the last commit (SCpubr_2.0.2.9000), and the behaviour did not change

exp_Integrated <- readRDS("int_B-only.Rds") 
b_markers <- read.csv("B_markers.txt")
do_FeaturePlot(exp_Integrated, features = b_markers$IG_genes, legend.position = "right")

Hi @frac2738,

Interesting. Even if I download the CRAN version, it works fine within my system environment. I will have to delve into this with some more time. Thanks again for bringing this up and for the help!

Hi @frac2738,

I have committed a hotfix that probably solves the issue. To be honest, this was a rather hard to reproduce bug, as it only happened in some devices while in others not (also tested in other colleague's RStudio sessions).

Could you please give it a go downloading SCpubr with the latest commit and let me know if this fixed your issue? If so, it will roll out in the next update of SCpubr.

devtools::install_github("enblacar/SCpubr" ref = "e9eace273bec3e6518f82a091378bc2e380e5489")

Looking forward to the answer!
Enrique

I will do more testing in the coming days, but it seems to work now.

> do_FeaturePlot(exp_Integrated,c("CD8A","CD3E"),
+                order = TRUE, viridis.palette = "D",use_viridis = TRUE,
+                viridis.direction = -1, legend.position = "right", legend.length = 8)

Thank you for fixing it this quickly!

[enblacar]

Hi @frac2738,

Great news! Happy that it worked.

I will close this issue now. Please feel free to open a new issue if you encounter anything else. Given how obscure this error was to my checks, I could foresee other similar ones popping up in other functions. If you encounter them, I would really appreciate if you let me know!

Best,
Enrique
