cf_append_cols {flowWorkspace} | R Documentation

## Append data columns to a flowFrame

### Description

Append data columns to a flowFrame

### Usage

    cf_append_cols(cf, cols, cred = NULL)

### Arguments

`cf` | A `cytoframe`.
`cols` | A numeric matrix containing the new data columns to be added. Must has column names to be used as new channel names.

### Details

It is used to add extra data columns to the existing flowFrame. It handles keywords and parameters properly to ensure the new flowFrame can be written as a valid FCS through the function `write.FCS` .

### Examples

      library(flowCore)
      data(GvHD)
      tmp <- GvHD[[1]]
      cf <- flowFrame_to_cytoframe(tmp)
      kf <- kmeansFilter("FSC-H"=c("Pop1","Pop2","Pop3"), filterId="myKmFilter")
      fres <- filter(cf, kf)
      cols <- as.integer(fres@subSet)
      cols <- matrix(cols, dimnames = list(NULL, "km"))
      cf <- cf_append_cols(cf, cols)
