Extracting information from multi-level lists - R
You really should be storing your data in a data frame or some such. I understand that the recursive structure is convenient when you're running tests in loops, but still. Fortunately there is a function that can do the translation: lst <- list(a=list(b=list(c0=list(d0=1:3, e0=4:6), c1=list(d1=7:9, e1=10:12)))) library(reshape2) DF <- melt(lst)...
3 level menu child link
jquery,drop-down-menu,multi-level
e.preventDefault(); prevents the links from performing their default action, going to their assigned url. That's why your links are working. You can change you query to '.menu > li > a' to only select the top level of links. <script> (function($){ $('.menu > li > a').click(function( e ){ e.preventDefault(); $(this).parent('li').find('ul:first').slideToggle();...
my mysql query to return multiple totals based on multiple clauses throws up an exception
You're missing the JOIN statements between the subqueries. Also, you can't have two FROM clauses. And you're missing the join conditions. SELECT a.Atotal, b.Btotal, c.Ctotal, u.userID, t.typeID FROM users AS u JOIN (SELECT ul.userID, COUNT( ul.listingID ) AS Atotal FROM tbl_user_listing AS ul LEFT JOIN tbl_listing_type AS t ON ul.listingID...
Descriptive Statistic for Multilevel (clustered) Data

If I understand well, what you want is to compute a variable at the level of the district and then attribute it to the school level. I hardly understand the rest of your post. You do that in base R using successively aggregate and merge . Given that you already...
Sort multi-level list in C# where the inner layer contains a list of typed objects
OK thanks for all the answers. I looked into LINQ a little and came up with a really simple statement that served my purpose: var groupedActivities = activities.GroupBy(p => p.ProjectnumberUnformatted); with this, I get an enumeration containing other enumerations of typed Activity objects and can then iterate through those sub-enumerations...

Optimization error for pymc3
bayesian,pymc,multi-level,pymc3
The error means the optimization algorithm finished but returned values that don't make any sense. Usually this is because the maximum isn't well defined. However, this actually worked fine for me. What versions do you have? I have python 2.7, latest pymc3, theano 0.7.0, scipy 0.13...
How to implement a 3 level dropdown with optgroup in yii?

Select2 with yii is the best known solution. So far it works only for 2 levels. In the given link you might find also a 2 dimentional optgroup setting. If you need a 3-level selection, then use two level select2 and a dependent dropdown for a 3rd level. Update Use...
I would like to convert the input (scheme like representation of lists) into multilevel linked lists? Can anyone help me with the C++ code for this?
The solution will almost certainly be a recursive one. Given a node definition, you will need a payload (the number), a next pointer (for items at the same "level") and an under pointer (for the sub-list). So you simply iterate over the incoming tokens. When you find a number, you...
