apply method for ncdfFlowSet (for internal use)

Description

It is equivalent to fsApply. But the latter could cause memory issue when FUN returns a flowFrame. ncdfApply writes to a new cdf file instead of memory. Thus it will return a ncdfFlowSet object.

Usage

## S4 method for signature 'ncdfFlowSet'
ncfsApply(x, FUN, ..., use.exprs = FALSE,
  ncdfFile = NULL)

Arguments

Details

When the function given by argument "FUN" does not return the entire flowFrame object with the same size of the original one (such as compensate,transform...), fsApply should be used instead.

Examples

data(GvHD)
nc <- ncdfFlowSet(GvHD[1:2])

#use fsApply when FUN does not return a flowFrame 
fsApply(nc, nrow)
fsApply(nc, range)

#use ncfsApply when FUN returns a flowFrame
lgcl <- logicleTransform( w = 0.5, t= 10000, m =4.5)
translist <- transformList(c("FL1-H", "FL2-H"), lgcl)
nc1 <- ncfsApply(nc, transform, translist)
