#Group(name, opts = {}) ⇒ Object

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) ⇒ Object

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) ⇒ Object

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)
