_D_e_s_c_r_i_p_t_i_o_n:

     Display name, class, size, and dimensions of each object in a
     given environment.

_U_s_a_g_e:

     ll(pos, ...)
     ## Default S3 method:
     ll(pos=1, unit=c("KB","MB","bytes"), digits=0,
             dimensions=FALSE,function.dim="", ...)
     ## S3 method for class 'data.frame':
     ll(pos, ...)
     ## S3 method for class 'list':
     ll(pos, ...)

_A_r_g_u_m_e_n_t_s:

     pos: environment position number, environment name, list, or data
          frame.

    unit: required unit for displaying object size: "KB", "MB",
          "bytes", or first letter.

  digits: number of decimals to display when rounding object size.

dimensions: whether object dimensions should be returned.

function.dim: value to report as the dimension of function objects.

     ...: passed to 'ls()'.

_D_e_t_a_i_l_s:

     A verbose alternative to 'ls()'.

_V_a_l_u_e:

     A data frame with named rows and the following columns: 

   Class: object class.

      KB: object size _(see notes)_.

     Dim: object dimensions _(optional)_.

_N_o_t_e:

     The name of the object size column is the same as the unit used.

     Objects of class 'classRepresentation',
     'ClassUnionRepresentation', and 'grob' do not have a defined size,
     so 0 bytes are assumed for those.

_A_u_t_h_o_r(_s):

     methods contributed by Jim Rogers

_S_e_e _A_l_s_o:

     'ls' displays names of objects in a given environment.

     'elem' and 'env' are related to 'll'.

_E_x_a_m_p_l_e_s:

     ll()
     ll(all=TRUE)
     ll("package:base")
     ll("package:base")[ll("package:base")$Class!="function",]
