Only show genes not located on X or Y chromosome - subset

[Bine]

Dear all,

Not sure what I am doing wrong, but I need your help.
I would like to exclude from my dataset any genes located on the X and Y chromosome.
I tried this, but still it is showing X and Y genes. Not sure why it is not working, has anyone an idea?

dataset<-dataset[dataset$chromosome_name!="X"|dataset$chromosome_name!="Y",]

Thanks so much!

Use "and" (&) instead of "or" (|), otherwise the logical expression always evaluates to TRUE

If you need more specific help, please provide a proper REPRoducible EXample (reprex) illustrating your issue.
