Error of fg.load.plink

[gangxuehzau]

Hi,
Sorry to bother you. when I loading genotype from plink files (bed,bim,fam),
I got an error about 【Error in .rowNamesDF<-(x, value = value) : duplicate 'row.names' are not allowed In addition: Warning message: non-unique value when setting 'row.names】,however, I found these plink files can be loaded into the variable which I define. so should I go further analysis regardless of this error?
Thank you
Gang Xue
