Dear all,

I have a file that is summary.txt(I have attached it) .we can read
 this file using-

 dfa=read.table("summar.txt",fill=T,colClasses =
"character",header=T)

 In V10 column I have  ASCII values which I want to convert into decimal
 numbers -

my  data frame(dfa) which is like-

     V7 V8  V9  V10
1    0  1   G    `
2    0  1   T    a
3    0  1   C    a
4    0  1   A    a
5    0  1   G    _
6    0  1   G    Z
