ExplicitRepresentation Accessors

## S4 methods for signature 'ExplicitRepresentation'
## x[i,j]

## further methods see below

## S4 method for signature 'matrix,dgRMatrix'
x %*% y

## S4 method for signature 'dgRMatrix,numeric'
x %*% y

`x`	an explicit representation in dense or sparse format
`i`	integer vector or character vector with a subset of the sample indices or names
`y`	in the first case and explicit representation and `x` is a `matrix`, for the second case a numeric matrix and x is an explicit representation
`j`	integer vector or character vector with a subset of the feature indices or names

see details above

: x[i,]: return a KernelMatrix object that only contains the rows selected with the subsetting parameter i. This parameter can be a numeric vector with indices or a character vector which is matched against the names of x.
: x[,j]: return a KernelMatrix object that only contains the columns selected with the subsetting parameter j. This parameter can be a numeric vector with indices or a character vector which is matched against the names of x.
: x[i,j]: return a KernelMatrix object that only contains the rows selected with the subsetting parameter i and columns selected by j. Both parameters can be a numeric vector with indices or a character vector which is matched against the names of x.

: %*%: this function provides the multiplication of a dgRMatrix or a sparse explicit representation (which is derived from dgRMatrix) with a matrix or a vector. This functionality is not available in package Matrix for a dgRMatrix.
