1.8.0 is ready for download now. The key new feature in 1.8.0 is support for
calculating the statistical median in the rel.group stream operator. For example, given
this test.csv input file:
string:name,int:value
fred,1
fred,5
betty,10
wilma,1
wilma,2
wilma,3
wilma,4
...this r17 script...
io.file.read('test.csv') | rel.from_csv() | rel.group(median value) | rel.to_csv();
...yields...
betty,10
fred,1
wilma,2
rel.group(median ...) also works all the other data types, including strings.
As always, please send feedback and bug reports to info@rseventeen.com.
