I love interactive pivot tables. That is the number one reason why I keep using spreadsheet software. The ability to look at data quickly in lots of different ways, without a single line of code helps me to get an understanding of the data really fast.
Perhaps I can do the same now in R as well. At yesterday’s LondonR meeting Enzo Martoglio presented briefly his rpivotTable package. Enzo builds on Nicolas Kruchten’s PivotTable.
