Hi R Users,

I tried to use sql in R;  test1 works well, 
test1 <- sqldf("select * from r where V1 like '%GCCATGTCAGCACACTACC%TGAAACCTTTAACTATTT%'")
test2 <- sqldf("select * from r where V1 like markerinfo$flank1[1] ")

but I want to store the search content in a markerinfo file as shown below
> markerinfo$flank1[1]

However, test2 does not work well.
How to make test2 work?
Thank you,
