Internal function: Compute a desired compositional margin
Description
This generic function should select the selected type of margin based on the class of the dataset and the specified margin type.
Usage
gsi.margin(X,...)
## S3 method for class 'acomp'
gsi.margin(X,what,...,margin="acomp")
## S3 method for class 'rcomp'
gsi.margin(X,what,...,margin="rcomp")
## S3 method for class 'aplus'
gsi.margin(X,what,...)
## S3 method for class 'rplus'
gsi.margin(X,what,...)
Arguments
X |
The dataset to take the margin from. |
what |
The indices xor column names to be kept. |
margin |
The type of marginalisation to be used. Possible values are: '"sub"', '"rcomp"', '"acomp"' and an index xor a name of a variable in the dataset. |

Value
