## Getting and setting the channel and image names

### Description

Methods to get and set the names of individual channels or the names of individual images.

### Setting and getting the channel names

In the following code, `x` is a CytoImageList object containing one or multiple channels. The channel names can be replaced by `value`, which contains a character vector of the same length as the number of channels in the images.

`channelNames(x)`

  Returns the names of all channels stored in `x`

`channelNames(x) <- value`

  Replaces the channel names of `x` with `values`. For this, `value` needs to have the same length as the number of channels in `x`

### Setting and getting the image names

Here, `x` is a CytoImageList object. The element names can be replaced by `value`, which contains a character vector of the same length as the number of images. In case of the CytoImageList object, elements are always images.

`names(x)`

  Returns the names of all images stored in `x`

`names(x) <- value`

  Replaces the image names of `x` with `value`. For this, `value` needs to have the same length as `x`
