I have a list of SNP rs ids (>1M) for which I would like to find respective CHR and POS information on Hg38. Can you please suggest how I can obtain this information? Thanks in advance Code should be placed in three backticks as shown below

# include your problematic code here with any corresponding output 
# please also include the results of running the following in an R session 

sessionInfo( )

You need the SNPlocs.Hsapiens.dbSNP144.GRCh38 and BSgenome packages for that. See ?snpsById after loading BSgenome.
