Question on re-indexing data for graphing
Hi, A file contains data for 1975-2012 of housing prices across a panel of countries. However, it's indexed to 2005, so each country's housing price series converges to 100 in 2005, then they spread apart again to 2012. This makes graphing all data series on one chart for comparison's sake somewhat awkward and unintelligible. Without the original data, a. could one properly reindex the data from 1975 in a statistically correct manner, and b. how could someone do this in R? Posted this in cross-validated, but if there is a better forum for this question, just let me know. Thanks for any help! -------------- next part -------------- An HTML attachment was scrubbed...
