## Get samples

### Description

Fetch a subset of samples from a given data structure

### Usage

    getSamples(x, y, ...)

### Arguments

`x` | the matrix of sample data to subset. If `x` is a vector it is interpreted as a matrix. `x` can also be of class `"ExpressionSet"`.
`y` | which sample(s) to use as data. Can be a vector of characters matching sample names, integers indicating which samples to choose, or a mixture of the two. If not supplied, all samples will be used.
`...` | Arguments to be passed to methods (see `getSamples-methods`): `element` which element of `AssayData` to use for a given `ExpressionSet` input (default is "exprs") `order` vector of characters, specifying on which column(s) to order the sample data. If NULL (default), the data will be returned without ordering enforced. `...` other arguments passed are not handled at this time.

### Value

Returns a matrix of values corresponding to a subset of samples from the data supplied, where columns correspond to samples. Function halts if no samples to return.
