supp: Merge CDISC Supplemental Data

In metrumrg: Pharmacometric Tools for Data Preparation, Modeling, Simulation, and Reporting

Description

Generic, with method for data.frame and keyed.

Within CDISC SDTM, data sets SUPPxx have a reasonably fixed relation to their counterparts xx, enabling an automated merge. The method for data.frame defaults to the method for keyed, which returns the merge of the two data sets.

Usage

 ## S3 method for class 'data.frame'
supp(
 	x,
 	suppx,
	...
 )
 
## S3 method for class 'keyed'
supp(
 	x,
 	suppx,
 	value= 'QVAL',  # possibly QORIG or QEVAL
	...
 )

Arguments

x	primary CDISC data set
suppx	supplemental CDISC data set
value	name of column in supplemental set where attribute names are stacked
...	ignored

Value

keyed data.frame
