check_reduce_raw_data: Check and Reduce the Observed Data

In dRiftDM: Estimating (Time-Dependent) Drift Diffusion Models

Check and Reduce the Observed Data

Description

Checks a data set that is considered an "observed data set". Used in the internals of dRiftDM. When calling this function, unncessary column names are stripped away.

Usage

check_reduce_raw_data(obs_data, b_coding_column, u_value, l_value)

Arguments

obs_data	a data.frame
b_coding_column	a single string, indicating which column of obs_data indicates how each RT corresponds to the boundaries.
u_value, l_value	the value within the b_coding_column column that specifies the upper/lower boundary

Details

Checks:

• if obs_data is a data.frame

• if "RT", b_coding_column, and "Cond" column are present

• when IDs are present, if each ID has values on each condition. At the same time unused factor levels are dropped drop_levels_ID_column

• If all columns are there, the data set is reduced to the relevant ones

• for missing Values, and drops rows with missing values

• if "Cond" is of type character, and if not casts it to character

• if RT is of type numeric, and of not casts it to numeric

• RTs are >= 0

• that the values in b_coding_column match with u_value and l_value (casts the column if necessary)

• if b_coding_column has only 1 or 2 unique values

Value

the obs_data for convenience (with edits as listed under Details).
