gs_pop_get_count_fast is more useful than getPop. Returns a table of population statistics for all populations in a GatingHierarchy/GatingSet. Includes the xml counts, openCyto counts and frequencies.

  statistic = c("count", "freq"),
  xml = FALSE,
  subpopulations = NULL,
  format = c("long", "wide"),
  path = "full",

gs_pop_get_count_with_meta(x, ...)



a GatingSet or GatingSetList


character specifies the type of population statistics to extract.(only valid when format is "wide"). Either "freq" or "count" is currently supported.


logical indicating whether the statistics come from xml (if parsed from xml workspace) or from openCyto.


character vector to specify a subset of populations to return. (only valid when format is "long")


character value of c("wide", "long") specifing whether to origanize the output in long or wide format


character see gs_get_pop_paths


additional arguments passed to gs_pop_get_count_fast


gs_pop_get_count_fast returns a data.frame with columns for the population name, xml derived counts, openCyto derived counts, and the population proportions (relative to their parent pouplation).

a data.table of merged population statistics with sample metadata.


gs_pop_get_count_fast returns a table population statistics for all populations in the gating hierarchy. The output is useful for verifying that the import was successful, if the xml and openCyto derived counts don't differ much (i.e. if they have a small coefficient of variation.) for a GatingSet, returns a matrix of proportions for all populations and all samples
