Iterating over file lines
I am attempting to iterate over a file, processing it line by line.
In my function below, I am only getting the first item over and over
and over again from my test file rather than subsequent lines. How
can I modify this to read lines sequentially?
==
iteratefile <- function(file) {
f.con <- file(file)
on.exit(close(f.con))
while( length(readln <- readLines(f.con, 1)) > 0 ) {
x <- unlist(strsplit(readln, " "))
print(x[1])
}
return(invisible())
}
iteratefile("test.txt")

I am working with version...
