Dear R community,

to combine data sets of hierarchical, nested nature (i.e., data sets
linked by, for example, the variable "study ID" and then also by
"outcome_variable_1" and "outcome_variable_2") I can use the match files
command in SPSS. What is the equivalent command / function in R? Is it
the merge function, or the match function? The more I read, the more
confused I become..

Thank your for help in advance!
