Dear list, We have a number of files containing similarly structured data: file1: A B C 1 2 3 4 5 6 file2: A B C 7 8 9 10 11 12 ... etc My part of R receives all these data as an array: 1,2,3... 12 together with info about dimensions (row,col,fileN) . ( Converting the data into 3D cannot simply done by: array(x, c(2,3,2)) because breaks the structure (e.g. 1,3,5 is type mismatch)

Hi all, I decided to check the responsiveness of the pure Ruby vs C extension versions of win32-changenotify. I setup this little file generator program: a = [] 10.times{ |n| a << Thread.new{ File.open("File_#{n}", ''w''){ |fh| fh.puts "test #{n}" } } } a.each{ |t| t.join } The pure Ruby version did not do so well. In some cases it

Hi Dave, That's rather frustrating. I've found vroom (from the package vroom) to be helpful with large files like this. Does the following give you any better luck? vroom(file_name, delim = ",", skip = 2459465, n_max = 5) Of course, when you know you've got errors & the files are big like that it can take a bit of work resolving things.
