Description

#'########################################################################### Function to estimate the cost of patches when IPD is in long format using a IPD data of long format

  the_columns,
  ind_part_data_long,
  name_med,
  brand_med = NULL,
  dose_med,
  unit_med = NULL,
  no_taken,
  freq_taken,
  timeperiod,
  unit_cost_data,
  unit_cost_column,
  cost_calculated_per,
  strength_column,
  list_of_code_names = NULL,
  list_of_code_freq = NULL,
  list_of_code_dose_unit = NULL,
  list_of_code_brand = NULL,
  eqdose_cov_tab = NULL,
  basis_strength_unit = NULL
)

Arguments

the_columns	columns that are to be used to convert the data from long to wide
ind_part_data_long	IPD
name_med	name of medication
brand_med	brand name of medication if revealed
dose_med	dose of medication used
unit_med	unit of medication ; use null if its along with the dose
no_taken	how many taken
freq_taken	frequency of medication
timeperiod	time period for cost calculation
unit_cost_data	unit costs data
unit_cost_column	column name of unit cost in unit_cost_data
cost_calculated_per	column name of unit in the cost is calculated
strength_column	column column name that contain strength of medication
list_of_code_names	if names is coded, give the code:name pairs, optional
list_of_code_freq	if frequency is coded, give the code:frequency pairs, optional
list_of_code_dose_unit	if unit is coded, give the code:unit pairs, optional
list_of_code_brand	if brand names are coded, give the code:brand pairs, optional
eqdose_cov_tab	table to get the conversion factor for equivalent doses, optional
basis_strength_unit	strength unit to be taken as basis required for total medication calculations

Value

the calculated cost of tablets along with original data
