flowCore parameters( ) function does not appear to exist

While creating flow frames using the flowFrame function I noticed that while I could change the parameters of an existing flow frame using

"parameters(flowFrame)<-" , I could not use the function parameters(flowFrame) to extract the AnnotatedDataFrame.

When I attempt to use the flowCore parameters() function, the only function available is the parameters() function from the package

'modeltools'. Below is some code from my most recent R session:

> frames <- lapply(dir(path = "/Users/nruthen16/Desktop/MRD-/134", full.names=TRUE), read.FCS)
> frames[[1]]
flowFrame object 'd339ff7a-04fc-4f44-a74f-862590f6e7af'

I realized that the parameters function from modeltools interferes with calling the parameters function from flowCore since they are referred to by the same name in both packages.

The solution is simple: 

You can specify which parameters function you would like to use by using
