Get groups averages.

get_group_averages() is a wrapper function to return group averages for the filtered peak table.

Usage

get_group_averages(mpactr_object)

Arguments

mpactr_object

The mpactr object that is created by calling the import_data() function.

Value

a data.table reporting the average and relative standard deviation across biological groups and technical replicates within each group.

Examples

data <- import_data(
  example_path("coculture_peak_table.csv"),
  example_path("metadata.csv"),
  format = "Progenesis"
)

data_filter <- filter_group(data, group_to_remove = "Blanks")
#> ℹ Parsing 1303 peaks based on the sample group: Blanks.
#> ℹ Argument remove_ions is: TRUE.Removing peaks from Blanks.
#> ✔ 796 ions failed the Blanks filter, 507 ions remain.

group_averages <- get_group_averages(data_filter)
head(group_averages)
