Is there a collections library in R that has the rough equivalent of what is in Java's is in java.util.Collections:
Various Distionaries
Various Trees
Various Bags
etc.
As far as I know, there is no such package that implements all the features of collections. Dataframes are the easiest and fun way to manipulate data. However, we can use lists for most of the functionality of linked-lists, stack and queues. This is how it is done.
Edit: For optimal results, implementation of linkedlists using lists is not recommended because of the way in which R allocates memory.
Hope it helped!

right now I have a big project with legacy C/C++ source codes. There are many global variables spread in different functions. In order to analyze the code, I need a tool which can take a look into these functions, check what local/global variables are used and modified in this function, and then better show theses interfaces graphically.
Does anyone have experience with this kind of analysis and know accordingly the tool names? I've tried Understand from SciTools, but it cannot deliver this kind of report.
Thanks!

I've recently inherited a collection of PL/SQL packages/procedures. Most operations involve one procedure calling another procedure which calls a third procedure, etc. I'm sure it made sense originally, but I'm struggling to get a good overall view.
Does anyone know of any software that maps/diagrams out the permutations of procedure call stacks in a visual way?
Found out about a view called dba_dependencies from http://www.dba-oracle.com/d_dba_dependencies.htm which appears to contain a raw form much of what I'm looking for. (The one drawback is it shows what packages are called by a specific package, not what procedures in a package are called by a specific procedure in a package.)

I would like to generate random tone sequences in R (likewise https://en.wikipedia.org/wiki/Twelve-tone_technique) for creating rule-based items. I'm interested, if someone could suggest R packages, which could sonify data for making melodies based on number sequences (for pitch and duration of a tone).
Here is a package to analyze music, that might help.
Here is an example you can try out.
Replicating something similar like the answer to this questions is maybe rather what you want. There the OP requests code to play the happy-birthday song in R. They code in the answer has, notes, pitch and duration, that you can easily define by yourself and sample randomly from to generate a song.
I think that it might be simpler to do most of these things in python.
Hope this helps!

I'm trying to learn to write elegant Standard ML code by reading others' code or projects. Does anyone know of some good code/projects?
I found the MLton compiler to be a great source for learning the module system.
The Twelf theorem prover also has a lot of high quality examples.
The standardml github account has a number of projects of varying quality. Somehow my sml-ext library ended up there. I'm not sure how.

I want to make a Vocabulary Trainer and I was thinking about the best way to do it. First I searched some translation APIs to use, to avoid having to build my own dictionary, but I found that most of them are paid and some are free but have limitations.
So, I think the best way is to make my own dictionary, which also allow me to work offline, but I wonder if there is any free database of English-Spanish words to avoid starting from scratch.
Do you know any?
Thanks a lot!
You could try http://www.omegawiki.org/ as they claim this:
The aim of our project is to create a dictionary of all words of all languages, including lexical, terminological and ontological information. Our data is available in a relational database, as a result it is possible to use the data for many purposes.
