Dear Ista I have searched about the problem and came to know that we can make a list of our file names.But the thing is I am using this code-
define<- function() { repeat{ hojy=readline("Enter the name of your file: ") if(file.exists(hojy)==T) {return(hojy) break} else print("File does not exist.Please enter again")} } for(i in 1:100){ df=read.table(define(),fill=T,colClasses = "character") df$V6 <- sapply(df$V6, function(a) paste(as.integer(charToRaw(a)), collapse = ' '))} so here i am using a function which is asking user to input the file name.But I was thinking that if I will delete this function and will use the read.table like this- for(i in 1:100){ df=read.table($i.out,fill=T,colClasses = "character") df$V6 <- sapply(df$V6, function(a) paste(as.integer(charToRaw(a)), collapse = ' '))} if you will check this line- df=read.table($i.out,fill=T,colClasses = "character") I have used $i.out here and every time in for loop i will be 1 then 2 then 3 till 100.So it will become very easy.But this $ sign is not working in the R.Can I do this thing in R.
