Hi,
Could someone please tell me whether the fragment_length in the featureSet
of pd.mapping250k.sty is the fragment_length of the sample? Are there
documentations available for looking up the meanings of each field?
Some rows have NAs for most the fields even though the allele information is
known, is this expected?
Thanks so much for your help!
library("pd.mapping250k.sty")
con = db(pd.mapping250k.sty)
dbListFields(con, "featureSet")
[1] "fsetid" "man_fsetid" "dbsnp_rs_id" "chrom"
[5] "physical_pos" "strand" "cytoband" "allele_a"
[9] "allele_b" "gene_assoc" "fragment_length" "dbsnp"
[13] "cnv"
dbGetQuery(con, "select * from featureSet order by fsetid desc limit 2")
fsetid man_fsetid dbsnp_rs_id chrom physical_pos strand cytoband
