Retrieve and set channel names from object
This generic function reports or updates the channels in an object.
channelNames(object, ...) channelNames(object, ...) <- value
- An S4 object, typically derived from class
- Replacement value, either a character vector (to re-order existing channel names or a named character vector or list (to change channel names from the vector elements to the corresponding names).
- Additional argument, not currently used.
channelNames returns the names of the channels in a defined
order. Change the order using the replacement method with a permuation
of the channel names as
value. Rename channels using the
replacement method with a named list, where the vector elements are a
permutation of the current channels, with corresponding names the new
identifier for the channel.
## channelNames default to alphabetical order of channels obj <- NChannelSet( R=matrix(runif(100), 20, 5), G=matrix(-runif(100), 20, 5)) channelNames(obj) channelNames(obj) <- c(Gn="G", Rd="R") ## rename channelNames(obj) channelNames(obj) <- c("Rd", "Gn") ## reorder channelNames(obj) all(assayData(obj)[["Gn"]] <= 0) all(assayData(obj)[["Rd"]] >= 0)
