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!
