Re: [R] Can R read Word fonts and comments?

It’s my understanding that docx and xlsx files are zipped containers that have their data in XML files. You should try unzipping one and examining it with a viewer. You may then be able to use pkg:XML. — David. > On Jul 1, 2016, at 3:13 PM, Bert Gunter wrote: > > No,

Hint: It's much more efficient not to loop and generate random data in a single call only once -- then make your samples. (This can even often be done with different distribution parameters, as in many cases these can also be vactorized) Example: ## 1000 random samples of size 100 >

Re: [R] How to identify runs or clusters of events in time

Mark, I did something similar a couple of year ago by coding non-events as 0, positive events as +1 and negative events as -1 then summing the value through time. In my case the patterns showed up quite clearly and I used other criteria to define the actual periods. Clint Clint Bowman

Hi William, I tested plyrs dlply function, and it seems to have have an O(N* log(R)) complexity (tested for R=N) so I do not know if N is the number of rows or nr of categories. For the data.frame example with 2e5 rows and 2e5 categories it is approx. 10 times faster than split. Still, it is 10
