error  in function ‘Identify_Conserved_CCI1’ ，because no HOM_matrix.rda file ？

I perform Identify_Conserved_CCI1 function to identify interactions。but with error 

1. Identify_Conserved_CCI1(species1_cci = SingleCellSignalR_mouse_result, 
 .     species2_cci = SingleCellSignalR_zebrafish_result, conserved_cell_types_df = conserved_cell_types_mm_zf, 
 .     species_name1 = "mm", species_name2 = "hs")
2. load(system.file("extdata", "HOM_matrix.rda", package = "CACIMAR"))
