CommPath data erro,can you tell me how to resolve?

[sunxm9]

tumor.obj <- createCommPath(expr.mat = ex,

•                         cell.info = label, 
  

•                         species = "hsapiens")
  

Error in .m2sparse(from, "dgC") : invalid type "character" in R_matrix_as_sparse() my data seems as same as your sample,but it doesn't work

[sunxm9]

class(label) [1] "factor" class(ex) [1] "matrix" "array"

Sorry for the late response. Could you kindly furnish an example dataset that I can utilize to replicate the error and debug the package?

Best, Yonghui
