In ncdfFlow: ncdfFlow: A package that provides HDF5 based storage for flow cytometry data.

Description

These functions are mainly for internal usage and normally not to be used by users.

Usage

## S4 method for signature 'ncdfFlowSet,character'
getIndices(obj, y)

## S4 method for signature 'ncdfFlowSet'
initIndices(obj)

## S4 method for signature 'ncdfFlowSet,character,logical'
updateIndices(obj, y, z)

Arguments

obj	ncdfFlowSet object
y	character sample name
z	logical vector to be assigned.

Value

a logical vector.

Examples

data(GvHD)
nc <- ncdfFlowSet(GvHD[1:2])
sn <- sampleNames(nc)[1]
nrow(nc[[sn]])
getIndices(nc, sn) #initial index is NA 
#subset with filter
library(flowStats)
morphGate <- norm2Filter("FSC-H", "SSC-H", filterId = "MorphologyGate",scale = 2)
nc1 <- Subset(nc, morphGate)
ind <- getIndices(nc1, sn)
# all.equal(sum(ind), nrow(nc1[[sn]]))
initIndices(nc1)
getIndices(nc1, sn) #reset indices
