Error in validityMethod(as(object, superClass)) : object 'Matrix_validate' not found

I just try to use :

scRNA <- FindNeighbors(scRNA, dims = pc.num)

and

scRNA.counts <- Read10X(data.dir = "filtered_feature_bc_matrix")

and both of them gives error like :

Error in validityMethod(as(object, superClass)) :    object 'Matrix_validate' not found

I guess these code totally run well in other's computer

so I wonder what's wrong with my code and how to fix it ?

Solution

  • Indeed, to solve the problem for you, it should be sufficient to do what @Mikael Jagan says:

    update.packages("Matrix")

    2nd thought: The above may not solve the problem entirely: As there are other packages involved, some of these may have to be re-installed (after the updating of Matrix).

    Can you post the output (or good summary of that if it's too long) of

     traceback()

    immediately after producing the error you are seeing?
