Append data columns to a flowFrame

fr_append_cols(fr, cols)

Arguments

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

Value

A flowFrame

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


  data(GvHD)
  tmp <- GvHD[[1]]

  kf <- kmeansFilter("FSC-H"=c("Pop1","Pop2","Pop3"), filterId="myKmFilter")
  fres <- filter(tmp, kf)
  cols <- as.integer(fres@subSet)
  cols <- matrix(cols, dimnames = list(NULL, "km"))
  tmp <- fr_append_cols(tmp, cols)

  tmpfile <- tempfile()
  write.FCS(tmp, tmpfile)
