Group(name,opts={}) click to toggle source

Shortcut interface for creating Data::Group

Example:

g = Group('mygroup', :data => [[1,2,3],[4,5,6]],
      :column_names => %w[a b c])   #=> creates a new group named mygroup

# File lib/ruport/data/grouping.rb, line 396
def Group(name,opts={})
  Ruport::Data::Group.new(opts.merge(:name => name))  
end

Grouping(*args) click to toggle source

Shortcut interface for creating Data::Grouping

Example:

a = Table(%w[a b c], :data => [[1,2,3],[4,5,6]])
b = Grouping(a, :by => "a")   #=> creates a new grouping on column "a"

# File lib/ruport/data/grouping.rb, line 385
def Grouping(*args)
  Ruport::Data::Grouping.new(*args)
end

Table(*args,&block) click to toggle source

Shortcut interface for creating Data::Tables

Examples:

t = Table(%w[a b c])   #=> creates a new empty table w. cols a,b,c
t = Table("a","b","c") #=> creates a new empty table w. cols a,b,c

# allows building table inside of block, returns table object
t = Table(%w[a b c]) { |t| t << [1,2,3] } 

# allows loading table from CSV
# accepts all Data::Table.load options, including block (yields table,row)

t = Table("foo.csv")
t = Table("bar.csv", :has_names => false)

# File lib/ruport/data/table.rb, line 928
def Table(*args,&block)
  table=
  case(args[0])
  when Array
    opts = args[1] || {}
    Ruport::Data::Table.new(f={:column_names => args[0]}.merge(opts),&block)
  when /\.csv/
    return Ruport::Data::Table.load(*args,&block)
  when Hash
    if file = args[0].delete(:file)
      return Ruport::Data::Table.load(file,args[0],&block)
    elsif string = args[0].delete(:string)
      return Ruport::Data::Table.parse(string,args[0],&block)
    else
      return Ruport::Data::Table.new(args[0],&block)
    end
  else
     Ruport::Data::Table.new(:data => [], :column_names => args,&block)
  end             
  
  return table
end
