Error in generate_homologs() / recode_character2()

[kimberle9]

Hello,

I'm having an error with the generate_homologs() function, stemming from recode_character2(). Any idea how to fix it? I tried changing parameters in generate_homologs, like setting the max_homologs to 1, adding a symbols_dict.... but always got the same error.

Otherwise, how can I run liana_wrap with a mouse dataset?

Many thanks in advance!

op_resource <- select_resource("Consensus")[[1]]
ortholog_resource <- generate_homologs(op_resource = op_resource,
                                       target_organism = 10090, 
                                       .missing_fun = "str_to_title")
