[R] automatic file input

[Bansal, Vikas]

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.


  

Thanking you,
Warm Regards

Hi Vikas,
please do make an effort to search for the answer before posting. A
google search for "R read multiple files" will give you everything you
need.

Best,
Ista
