subset data issue

[Chaelee1211]

I am trying to follow your protocol to conduct my analysis, but whenever I enter:
cellchat <- subsetData(cellchat)

I keep getting the following error:

Error in (function (cl, name, valueClass) :  
  assignment of an object of class "numeric" is not valid for @'data.signaling' in an object of class "CellChat"; is(value, "AnyMatrix") is not TRUE

No matter how much I search, I can’t find a similar error reference, and I don’t know how to resolve it.

When I check str([email protected]), it returns:num[0 , 0 ]
I am curious as to why this part is not being properly assigned.
