Question Posted 04/16/20:
I'm using the ADNI 1 GWAS data and I need to extract specific SNPs by their "rs" value under the variable SNP.Name. However, when I download the csv files into R the SNP Names convert to a numbered factor. I need these values to stay as characters and don't understand why this happens. Thank you for your help!

Please look at the plink files not csv files
