Newbie Question - Working with Arrays
Thanks, that is very helpful to get me started. -
Newbie Question - Working with Arrays
I was trying to do this using just basic arrays which I am more familiar with but it seems to be more complicated to try to do it that way. I haven't tried using hashes yet, I'm pretty new to perl, I only use it every now and then to do some things with data that excel and my stats program... -
Newbie Question - Working with Arrays
I'm trying to get started on some basic processing of data in array form. Basically this is a segment of what the data file looks like: 20070314180137 1003 1 641 1 20070314180137 1003 3 598 9 20070314180137 1003 4... -
comparing two arrays
Thanks so much, both of those suggestions work great. -
comparing two arrays
What I want to do is compare two arrays, one is just a vector with a single column, the other is multidimensional. I want to look at the 3 column in the multidimensional array and compare it to the single column in the other array and remove all of the lines from the multidimensional array for... -
SQL nested query
I have this line of code: $prelimResult = mysql_query("SELECT MAX(volume),MAX(issue),MAX(year) FROM articles",$db); That doesn't work quite how I want it to. I want it to find the largest volume, then the largest issue within that volume but instead this finds the largest volume... -
Split problem
mikevh, Sure that works for printing but that's not what I want to do with it. I'm going to be doing some more complicated things for which I need everything to be in one array where I can access specific elements. What Siberian suggested is too simple to work, but if I went along those... -
Split problem
That would work if I just wanted to print it out, but I want to be able to work with the individual elements later on. With that example it puts everything from a line into one element resulting in a single dimensional array, but I need to refer to specific elements like the "A" in... -
Split problem
I have a data file that looks something like this: 1 ABABAB 123456 2223 0.626903553299492 1 ABABAB 123465 60 0.0169204737732657 2 ABABAB 123546 60 0.0169204737732657 1 ABABAB 123564 9 0.00253807106598985 7 AABBAB 123645 8 0.00225606316976875 1 ABABAB 123654 13 0.00366610265087422 10 AAABBB... -
Playing a Video
I contacted EPrime about my problem and this is all they would tell me. I don't understand it, but perhaps it would be helpful: "The most common methods to call and access external rograms would be via OLE/COM Automation or via DLL calls via Declare statements. The use of these methods... -
Playing a Video
I'm actually using E-Basic (with the E-Prime software) but I'm told most VB commands will work. I'm using the E-Prime software to run an experiment, the software does not explicitely support playing a video stimuli but the E-prime support tells me that I can put in code like this... -
Array Problem
I have Learning Perl (and I read the entire thing) it doesn't even cover multidim arrays. I just got the Programming Perl book yesterday and am working on going through it. I read somewhere in the perldoc that @array[1]->[2] and @array[1][2] mean exactly the same thing, is this not the case... -
Array Problem
I can't figure out what is wrong with my code. It's supposed to create an array and print it out, but nothing prints, I don't get any error messages or anything. Here is my code: while (<>) { chomp; push @isr, [split/\t/]; } for my $i(0..$#isr){ if ($isr[$i][5] eq... -
Multidimensional Arrays
I'm not understanding how to create a multidimensional array by reading lines from a file. So say I have a file like this: 0 1 2 3 4 5 6 7 8 9 10 11 With lines of numbers separated by tabs. I would have something like this to read the lines from the... -
Problem creating tab delimited file
Nope, that results in exactly the same thing. Still have the M^'s
