fg_feat_cumsum: Converts cell counts into cumulated cell counts.

In aya49/flowGraph: Identifying differential cell populations in flow cytometry data accounting for marker frequency

Converts cell counts into cumulated cell counts.

Description

Converts the cell counts in a flowGraph object into cumulated cell counts; this is optional and can be done only for there is more than one threshold for one or more markers. This should also only be ran when initializing a flowGraph object as converting back and forth is computationally expensive. If the user is interested in seeing non- and cumulated counts, we recommend keeping two flowGraph objects, one for each version. This function simply converts e.g. the count of A+ or A++ into the sum of count of A+, A++, and A+++ or A++, and A+++.

Usage

fg_feat_cumsum(fg, no_cores)

Arguments

fg	flowGraph object.
no_cores	An integer indicating how many cores to parallelize on.

Details

fg_feat_cumsum returns the given flowGraph object with an adjusted count feature. As in our example,

Value

flowGraph object with cumulated counts.

Examples

 no_cores <- 1
 data(fg_data_pos30)
 fg <- flowGraph(fg_data_pos30$count, class=fg_data_pos30$meta$class,
                 prop=FALSE, specenr=FALSE,
                 no_cores=no_cores)

 fg <- flowGraph:::fg_feat_cumsum(fg, no_cores=no_cores)
