Summaries of amounts
Description
Summary of a vector of amounts, according to its underlying geometry.
Usage
## S3 method for class 'aplus'
summary( object, ...,
digits=max(3, getOption("digits")3), robust=NULL)
## S3 method for class 'rplus'
summary( object, ..., robust=NULL)
## S3 method for class 'rmult'
summary( object, ..., robust=NULL)
Arguments
object 

digits 
the number of significant digits to be used. The argument can also be used with rplus/rmult. 
... 
not used, only here for generics 
robust 
A robustness description. See robustnessInCompositions for details. The option is currently not supported. If support is added the default will change to getOption(robust). 
Details
The obtained value is the same as for the classical summary summary
,
although in the case of aplus
objects, the statistics have been computed in a
logarithmic geometry, and exponentiated afterwards (which just changes the mean, equivalent
to the geometric mean of the data set).
Value
A matrix containing summary statistics (minimum, the three quantiles, the mean and the maximum) of each component.
