...ssed. One has about 350,000 levels [yes, it's genetic association data]. The other will have about 4000 levels eventually, but is up to about 100 now. When the data were entered they were already ordered by this second index variable. Creating the index took about an hour on the 100-level, presorted variable and about 12 hours on the 350,000-level unsorted variable. I'm looking for advice on how to reduce this. Specifically 1/ would it be faster if the variable with more levels was the presorted one? 2/ would it be faster or slower if the index were created before adding all the data? 3...

SAS proc rank has ties options of high and low that would allow producing ranks of the type found in the sports pages, e.g., rank (c(1,1,2,2,2,2,3)) == 1 1 3 3 3 3 7 Could R support these ties.methods?

OK - this is a wild idea and wondering what it would take to make it possible. I get a lot of email from a lot of different people about a lot of different issues. What I need is a way to do some server side presorting of email into specific folders. I can build a LOT of Mozilla rules but that is too cumbersome for what I have in mind. Here's what I'm thinking - one classification of email is "customers" and what I want to do is to drag an email into the customers server side folder and...

Do you think I'd break a lot of people's filters if I removed the prefix? :) Anyone strongly for/against removing it? It seems kind of annoying to me whenever I happen to think about it. -------------- next part -------------- A non-text attachment was scrubbed...

As mentioned in another thread, I notice that the params used to control symlinks feel a bit inefficient and inelegant, and quite limited. I think there might be a good opportunity to simplify and also make their management in Samba more powerful and adaptable to use-cases. I'm guessing this list is a good enough starting point to propose a smb.conf param change to this area and see what

I have a large Excel file with SKU numbers (stock keeping units) and forecasts which can be mimicked with the following: Period <- c(1, 2, 3, 1, 2, 3, 4, 1, 2) SKU <- c("A1","A1","A1","X4","X4","X4","X4","K2","K2") Forecast <- c(99, 103, 128, 63, 69, 72, 75, 207, 201) PeriodSKUForecast <-

By default, Apple Mail downloads all e-mails from server's account. Previous versions of this client allowed to opt-out. The latest two versions? however, only allow to opt-out from downloading the attachments. The stress on the server is unbearable. We cannot ask users to be considerate: this is the default behaviour of Apple Mail. We need a server-side solution to the problem. Please
