Dear all, I am really sorry for not giving the input file because in my mail,I did not explain my problem in a best way.
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 converted into decimal numbers using this code- dfa$V10=lapply(dfa[,4], function(c) as.numeric(charToRaw(c))) Now I have a dataframe dfa with these columns something like this- 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.
