summary.aplus {compositions} | R Documentation |
Summary of a vector of amounts, according to its underlying geometry.
## 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)
object |
an aplus /rplus set of
amounts |
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). |
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).
A matrix containing summary statistics (minimum, the three quantiles, the mean and the maximum) of each component.
