How about this - I'm unsure of some of the variables - they seem a little
strange but I'm sure you can debug any issues in that respect - I just used
pretty much what you provided.
def read_data(num_in = nil, num_out = nil, num_lines = nil)
#This just looks a little nicer than the if .nil? == false
unless @inFile.nil?
#Either we are provided the number of lines to use or we use them all
num_lines ||= @inFile.length
#Instead of counting where we are we just limit our group to what we
want
myFiles = @inFile[0...num_lines]
#Use our limited dataset
File.foreach(myFiles) do |line|
arr = line.chomp.split(',')
float_array = arr.map { |x| x.to_f }
#Make a choice based on the num_in variable
if num_in.nil?
@file_data.push(float_array)
else
#Much simpler here - no need for the loops and temp vars
#Just grab what we need and move along
in_data << float_array[0...num_in]
out_data << float_array[num_in...(num_in+num_out)]
end
end
end
return @file_data
end
