Sorry, I'm not following you. In the examples, name.keyword is used for
the file names and appears to take a keyword from the FCS file as its
target, such as "SAMPLE ID". Maybe colname.keyword? Even then, I don't
understand how I could tell read.flowSet to read the keyword just
after the one it normally does to take the colnames. Maybe a grep
operation? The FCS keyword changes with each channel, the channel
number in the below example is augmented by one as you go along. 

[1] "AmCyan-A"

$`$P16N`   --------------> used by read.flowSet as colnames
 [1] "Indo-1 (Violet)-A"

$`$P16S`   --------------> would like to use instead
[1] "BlueUV-Live"
