Tip: pay more attention to what is stored in the R-Help archive and keep
a hardcopy of the Ref-card close to you. A colleague even posted the
newest version today.

Assunto: [R] For column values-Quality control
Dear sir,
I am struggling with a problem.Please help me.
Now I have a dataframe with these columns-
V7 V8 V9
V10
0 1 G
82
0 1 CGT
c(90, 92, 96)
0 1 GA
c(78, 92)
0 1 GAG
c(90, 92, 92)
0 1 G
88
0 1 A
96
0 1 ATT
c(90, 96, 92)
0 1 T
94
0 1 C
97
the values in column V10 corresponds to A,C,G T in column V9.I want only
those whose score is more than 91.so output of above should be-
V7 V8 V9
V10
0 1 GT c(90,
92, 96)
0 1 A
c(78, 92)
0 1 AG c(90,
92, 92)
0 1 A
96
0 1 TT c(90,
96, 92)
0 1 T
94
0 1 C
97
Can you please tell me the solution.
Thanking you,
Warm Regards
