I'm not sure I understand. If ssn is the only common variable, how do you determine which records match? If you do have the accident date info in both files, then it's a simple merge in Stata -- you can merge on multiple variables (see whelp merge) use accidentdata sort ssn accide...
Importing data in R programming means that we can read data from external files, write data to external files, and can access those files from outside the R environment. File formats like CSV, XML, xlsx, JSON, and web data can be imported into the R environment to read the data and pe...

I needed to compare two sheets and spent about 30 min writing code in Stata to do it. Then, even though I knew there were no differences, I decided there must be an easier way and found your tutorial. It took about 1 minute using conditional formatting. I never would have thought to ...
# geographical information system (gis) files (this is a special request) longlat <- read.dbf( "./Egypt/Standard DHS 2008/Supplemental/flat/EGGE5DFL.dbf" ) # convert all column names to lowercase names( longlat ) <- tolower( names( longlat ) ) # merge this cluster information ...
Importing your data into R to start your analyses: it should be the easiest step. Unfortunately, this is almost never the case. Data is stored in all sorts of formats, ranging from from flat files to other statistical software files to databases and we..
But if you’re really busy, the tl;dr is that I found out a way of combining tidy evaluation and functional programming to analyze potentially millions of files (as many as fit on your hard disk) without running out of memory in...
The Stata blog posts I referred to earlier provide lots of useful tips and tricks on how to creatively use -merge- that can also be used in this context of comparing files rather than combine them. Hope this helps, Maarten --- Maarten L. Buis WZB Reichpietschufer 50 10785 Berlin Germany...
