I've got 2 csv files on my hand ; the first listing restaurants, with 3 columns(coordinate x, coordinate y, restaurant name) and another listing deliveries (coordinate x, delivery coordinate y , name of the restaurante the delivery was done by).

I need to : 1) Display the number of deliveries made for each restaurant. 2) The average distance of the deliveries for each restaurant (distance being calculated by this formula = sqrt(sq(x1-x2)+sq(y1-y2) at least I figured something out :p)

For the first, I made a class which looks like this :

Then I'm trying to go trought the deliveries table and change the arraylist of objects so that when the string happens to be the same in a row and the arraylist object the object counts gets to +1. But it doesn't seem to work. Any tips appreciated for the step 2, also.

This time I have the problem that with a csv file which goes to 120 rows, I pass all that data in the constructor, but I haven`t find a way to put the 120 objects in a 60 x 20 grid.

Objet[] o;  
void setup() {  
 size(1000, 800);  
 table = loadTable("data.csv", "header");  
 o = new Objeto[table.getRowCount()];  
 for (int i = 0; i < table.getRowCount(); i++) {  
 int inde = i;  
  TableRow r = table.getRow(i);  
  String date = r.getString("date");  
  int num = r.getInt("num");  
  int time = r.getInt("time");  
  int score = r.getInt("score");  

  o[i] = new Objet(index, date, num, time, score);  
} 

I won't post my whole code, but here is the setup() snippet:

function setup() {
  canvas = createCanvas(680, 420);
  canvas.mousePressed(inWidth);
  background(51);
  // Calling noStroke once here to avoid unecessary repeated function calls
  noStroke();
  // iterate over the table rows
  for (var i = 0; i < clContext.getRowCount(); i++) {
    var category = clContext.get(i, "category");
    var statement = clContext.get(i, "statement");
    var polarity = clContext.get(i, "polarity");

 // split long statements that have '\r\n' in them and add the rest as a second or third line
    statement = split(statement, "[\\r\\n]+");

 // creates `display()` object from `Statement` constructor (not shown)
    statements[i] = new Statement(category, polarity, statement);
  }
}

I have tried various configurations based on native js, e.g., var array = sentence.split("\n").map(x => x.trim());, but that just throws an error that sentence.split is not a function. And now I've tried what's there now, including putting it in a for loop, from the Processing reference, but I have not found a solution that works. I can still run the sketch, but the line breaks don't work.

    Table stats;

    void setup() {
      stats = loadTable("ortiz.csv");
      for (int i = 0; i < stats.getRowCount(); i++) {
        // Gets an integer from row i, column 0 in the file
        int year = stats.getInt(i, 0);
        // Gets the integer from row i, column 1
        int homeRuns = stats.getInt(i, 1);   
        int rbi = stats.getInt(i, 2); 
        // Read a number that includes decimal points
        float average = stats.getFloat(i, 3); 
        println(year, homeRuns, rbi, average);
      }
    }

I've tried a way with importing the csv module and playing with that but I'm not sure that it's the same way as the book deal with.

Any help would be very appreciated! (Sorry for my skilless english) Thanks!

I am new to processing and new to programming in general. Can someone please help me with the code below?

I believe the error is related to the line with the max() function, which I need for the map function to properly import my data.

The error I keep getting back is "The method max(float,float) in the type PApplet is not applicable for the arguments (float)"

I have no idea what I am doing wrong....Thanks in advance.

I need to find a way to create a new node when the csv shows a new festival, but when it reads the same festival it needs to add 1 to a count, this also needs to happen per DJ.

I created a system that would count the festival but it will only work if my csv lists these festivals in order, so this wont work for the DJ's. I figured it might be usefull to create a 2-dimensional table but im not really sure how i can properly implement that in this code.

(Right now the "dj" nodes are not being created by a loop yet but are still static).

Any help would be greatly appriciated.

This is my main program:

Node[] nodes = new Node[1]; //These will be the DJ nodes

festNode[] festnodes = new festNode[0]; //These are the Festival nodes

festData[] festdatas = new festData[0]; //This is just a helper to supply the Festival nodes with data

header1, header2, header3

text1,2,3

text2,0,1

text3,0,0

into 2 arrays looking like this {{2,3},{0,1},{0,0}} and this {text1, text2, text3} Could anyone help me? Thanks a lot kamca

with the following fragment of code

  messagesFilename=language+".csv";
  Table table = loadTable(messagesFilename, "csv, newlines");      // i.e. file names 0.csv, 1.csv ...
  for (int index=0; index < table.getRowCount (); index++) {
    imageFilename[index]=table.getString(index, 0);
    imageTitle[index]=table.getString(index, 1);

    // Print what just loaded
    println(imageFilename[index] + " " + imageTitle[index]);
  }

I would expect output of the println to take \n into consideration and to be in the form of

[...]
04.jpg line1
line2
line3
05.jpg line1
line2
line3
[...]

but instead newlines (\n) are not properly interpreted and I get

[...]
04.jpg line1\nline2\nline3
05.jpg line1\nline2\nline3
06.jpg line1\nline2\nline3
07.jpg line1\nline2\nline3
08.jpg line1\nline2\nline3
[...]

Any suggestions?
