Error in scale_color_gradient2()

[ShashTrip1]

Reran some old code I had (last ran 1 month aga without any errors) however today it threw an error. Code below:

I ran: plotDAbeeswarm(da_results, group.by = "ident")

And it gave the following error:
converting group.by to factor...
Error in scale_color_gradient2():
! Discrete values supplied to continuous scale.

Hi @ShashTrip1 can you check if the 'ident' variable is a factor, character or numeric type. Pre-converting to character may help.

I encountered the same problem. I group.by = "celltype", but it still gave me the same error, even I converted "celltype" to character. Did you solve it?

[MikeDMorgan]

Your code states that the group.by variable is "ident" not "celltype".

I also met this problem when I run " plotDAbeeswarm":
Converting group_by to factor...
Error in scale_color_gradient2():
! Discrete values supplied to continuous scale.
ℹ Example values: NA, NA, NA, NA, and NA
Run rlang::last_trace() to see where the error occurred.

I check the 'ident' variable I used is a factor.
Do you have any suggestion?

[MikeDMorgan]

Yes - you have NA values in your variables, as stated in the error traceback.
