Hi everyone,

I have the following dataset for which I need to do a 1-by-1 match of companies (wo replacements) from group 1 to companies in the same province from group 2 with the closest assets in the last year from the year in variable 'rendate' (ignoring the differences caused by sequential order of the matching). To give a little more background the dataset spans from 1990-2011 but I have only included variables till 2000 in the example and id is the unique ID for each company. Also, in the variable 'changedname' 1 denotes "group 1" and 0 denotes "group 2".

I am not sure how I can go about the process except for doing a joinby to get the pairwise combinations (within each province) but I am stuck at incorporating in the code the part to capture the closest assets based on the previous year (from the year stored in 'rendate') and then generating the nearest possible match wo replacement. It would be helpful if I could get some ideas.
