Why does scatter does not read a file as a parameter and how do I classify my data?

function [ average ] = classifyData( file )

load(file);

xlabel('sepal length | sepal width | petal length | petal width');
ylabel('numeric data');
average = mean(file);
r = file;
c = {1,2,3,4,5};
scatter(r,c,'o');

Read data
data = csvread('../../Downloads/iris_data.csv')
For a scatter plot of column 2 vs 1
scatter(data(:,1), data(:,2))
and in 3D
scatter3(data(:,1), data(:,2), data(:,3))
To separate the data in two classes using kmeans clustering:
idx = kmeans(data, 2);
Show results
ind = idx == 1; scatter3(data(ind,1), data(ind,2), data(ind,3), 'b')
hold on
ind = idx == 2; scatter3(data(ind,1), data(ind,2), data(ind,3), 'r')
