util_check_group_levels: Check data for observer levels

Description

Check data for observer levels

Usage

util_check_group_levels(
  study_data,
  group_vars,
  min_obs_in_subgroup = -Inf,
  max_obs_in_subgroup = +Inf,
  min_subgroups = -Inf,
  max_subgroups = +Inf
)

Value

modified study data frame

Arguments

study_data

data.frame the data frame that contains the measurements

group_vars

variable the name of the observer, device or reader variable

min_obs_in_subgroup

integer from=0. optional argument if group_vars are used. This argument specifies the minimum number of observations that is required to include a subgroup (level) of the group variable named by group_vars in the analysis. Subgroups with fewer observations are excluded.

max_obs_in_subgroup

integer from=0. optional argument if group_vars are used. This argument specifies the maximum number of observations that is required to include a subgroup (level) of the group variable named by group_vars in the analysis. Subgroups with more observations are excluded.

min_subgroups

integer from=0. optional argument if a "group_var" is used. This argument specifies the minimum no. of subgroups (levels) included "group_var". If the variable defined in "group_var" has fewer subgroups it is split for analysis.

max_subgroups

integer from=0. optional argument if a "group_var" is used. This argument specifies the maximum no. of subgroups (levels) included "group_var". If the variable defined in "group_var" has more subgroups it is split for analysis.
