Hi dear experts, I have a general question in R, about the categorical variable such as Gender(Male or Female) If I have this column in my data and wanted to do regression model or feed the data to seqmeta packages (singlesnp, skat meta) , would you please let me know should I code them first ( male=0 and female=1) or R programming do it for me? Because when I didn't code them, R still can do the analysis without any error but I'm not sure it's correct or not? Thanks
