transpose_microbioevents: Transpose microbiology events dataset

Description

This function helps to transpose (rows to columns) microbiology events.

Usage

transpose_microbioevents(raw_df,
                                 key_columns,
                                 required_columns,
                                 transpose_key_column,
                                 transpose_value_column,
                                 fill="NA",
                                 non_empty_filter_column,
                                 remove_duplicates=TRUE)

Value

Data Frame

Arguments

key_columns

(Optional) Primary Key/ Key columns for duplicate check : Default Value = c('subject_id','micro_specimen_id','isolate_num', 'org_name','ab_itemid')

raw_df

A data frame containing microbiology events

required_columns

(Optional) columns should contain in final dataset : Default Value c('subject_id','hadm_id','micro_specimen_id', 'order_provider_id', 'chartdate','charttime', 'spec_itemid','spec_type_desc','storedate', 'storetime','test_itemid','test_name', 'org_itemid','isolate_num','org_name')

transpose_key_column

(Optional) The column that should be transposed ( - distinct values of that column will become separate columns) :Default 'ab_name'

transpose_value_column

(optional) Values of 'transpose_key_column' column :Default 'interpretation'

fill

(optional) Fill character for empty columns- Default : "NA"

non_empty_filter_column

(optional) Filter input dataframe where 'non_empty_filter_column' is not empty or na. Default :'ab_itemid'

remove_duplicates

(optional) Default :TRUE
