Just to forestall confusion amongst those who would like to use one of 
the functions called "describe"...

Hmisc package - describe
numeric
  name
  count of observations
  count of missing values
  count of unique values
  mean
  seven quantiles
  five lowest and highest values
discrete (factor or numeric with <= 10 unique values) -
  as for numeric, but
  no mean, quantiles or low/high values and
  including a frequency/percent display for each value.

psych package - describe
  item name
  item number
  number of valid cases
  mean
  standard deviation
  median

  kurtosis	(optional)
  standard error

prettyR package - describe
