Changes in version 1.5.4 (2019-03-29) User Visible Changes: * the provided variables (flowPloidyFiles, fpVac, fpBad) that list the filenames for the example data have been changed to functions with the same name. This was required to accomodate changes in the way R loads package code. As a consequence, users will now have to call the functions (i.e., `flowPloidFiles()`, note the parentheses) instead of refering to the variables (i.e., `flowPloidyFiles`). Changes in version 1.5.3 (2018-01-19) User Visible Changes: * two additional FCS files have been added: fpVac, which is useful in demonstrating gating; and fpBad, which is a very low quality file used in unit tests.
