Stata FrLink
-frlink- joins data across frames.
Contents
Usage
frlink 1:1 KEYVARS, frame(foo) frlink m:1 KEYVARS, frame(foo)
If the frame has differently-named key variables, try:
frlink 1:1 uid, frame(foo subid) frlink m:1 uid, frame(foo subid)
In either case, a link variable is created with the same name as the frame (foo in this case). To rename this variable, use the generate(varname) option.
frlink dir lists the available link variables. frlink describe LINKVAR describes a link variable.
A read-only view of values in the linked frame can be accessed like:
generate foobar = foo + frval(linkvar, bar)
See also the fralias and frget commands.
