Can anyone help me with this script error?

Question

[nuorain]

Hi, I tried to run this code but encounter the error.

gsva_matrix<- gsva(as.matrix(tcga_exp), gene_set,
                   method='ssgsea',kcdf='Gaussian',abs.ranking=TRUE)

Error in gsva(as.matrix(tcga_exp), gene_set, method = "ssgsea", kcdf = "Gaussian",  : 
  Calling gsva(expr=., gset.idx.list=., method=., ...) is defunct; use a method-specific parameter object (see '?gsva').

Can anyone help me out? Thank you very much. Best J
