I often see this problem where units stop working but I have not been able to produce a sequence of commands to reproduce it. However, I have found this commands fixes the issue:
I would like to post a simple solution for addition of functions, probably understandable to most of mma users. Evaluate[ ] would calculate the result. In[1]:= cs[x_] := Evaluate[Cos[x] + Sin[x]] In[2]:= cs[x] Out[2]=...
I am having this exact issue as well, in 11.3, but with ListPointPlot3D. I found the replacement rules with Missing[] or \\[EmptySet] got rid of the errors, but didn't actually make the plot. I ended up instead replacing the empty lists with a single...
If you do, feel free to ask me as many questions as you want.
I don't understand why {b, 0.01} is incorrect for an initial guess for b?
MyData = Import["myfile.xlsx", "Data", HeaderLine->1] Or if there's is no header line MyData = Import["myfile.xlsx", "DataSet"] Use menu Import/Path... if the file is in out of Mathematica 11.3 paths. Sorry it there's are errors, I wrote it...

The (N+1)th solution: {#[[1, 1]], Sequence @@ #[[All, 2]]} & /@ GatherBy[data1~Join~data2, First]
Thank you so much for the link and your quick reply!
