gtools-0.6.5 through gtools-0.6.9 Enhancements * Addressed the possible issue noted in issue #3 and the functions now use mata and extended macro functions as applicable. * `gegen varname = group(varlist)` no longer has holes, as noted in issue #4 * `gegen` and `gcollapse` fall back on `collapse` and `egen` in case there is a collision. Future releases will implement an internal way to resolve collisions. This is not a huge concern, as SpookyHash has no known vulnerabilities (I believe the concern raied in issue #2 was base on a typo; see [here](rurban/smhasher#34)) and the probability of a collision is very low. * `gegen varname = group(varlist)` now has a consistency test (though the group IDs are not the same as `egen`'s, they should map to the `egen` group IDs 1 to 1, which is what the tests now check for). * The function now checks numerical variabes to see if they are integers. Working with integers is faster than hashing. * The function is now smarter about generating targets. In prior versions, when the target statistic was a sum the function would force the target type to be `double`. Now if the source already exists and is a float, the function now checks if the resultimg sum would overflow. It will only recast the source as double for collapsing if the sum might overflow, that is, if `_N * min < -10^38` or `10^38 < _N * max` (note +/- 10^38 are the largest/smallest floats stata can represent; see `help data_types`). Bug fixes * `gegen` no longer ignores unavailable options, as noted in issue #4, and now it throws an error. * `gegen varname = tag(varlist)` no longer tags missing values, as noted in issue #5 * Additional fixes for issue #1 * Apparentlly the argument Stata passes to plugins have a maximum length. The code now makes sure chuncks are passed when the PATH length will exceed the maximum. The plugin later concatenates the chuncks to set the PATH correctly. * Fixed issue #1 * The problem was that the wrapper I wrote to print to the Stata console has a maximum buffer size; when it tries to print the new PATH it encounters an error when the string is longer than the allocated size. Since printing this is unnecessary and will only ever be used for debugging, I no longer print the PATH. * Debugging issue #1 on github (in particular, `env_set` on Windows). * Removed old debugging code that had been left uncommented * Improved out-of-memory message (now links to relevant help section).

The assertion fails because
gegentags missing values of rep, whileegendoesn't.From the help files: "The result will be 1 if the observation is tagged and never missing, and 0 otherwise", so I think MVs should have a tag of zero unless the
missingoption is included.The text was updated successfully, but these errors were encountered:
