select-FIMatrix: Subsetting of an FIMatrix
In TimToebrock/Rpriori: Implementation of the Apriori Algorithm
Description
Usage
Arguments
Value
Description
An FImatrix does contain the matrix of itemsets as well as the a vector that contains the support
for each itemset. Therefore, both are logically connected and when a FIMatrix is subsetted column-
wise the supported vector has to be subsetted as well.
Usage

## S4 method for signature 'FIMatrix'
select(x, i, j)
Arguments
x
Object of class FIMatrix.
i
Either the rows represented by their row number or a logical vector of length number of
row of FIMAtrix. If missing or NULL all rows are selected.
j
Either the columns represented by their columns numbers or logical vector of length
number of columns in FIMatrix. If missing or NULL all columns are selected.
Value
subsetted FIMatrix
