Re: Sorting Nested Vectors and filter out some
Hi...I get my nested vector from a database, then map a function that formats it and computes the deviation, actual data looks like below..so I don't have any keys within the the vector, ..would like to sort by index 5 in in each vector descending and if index 5 is N/A (not e.g a percentage)remove it from the list [[151819 ANTI HUMAN GLOBULIN SERUM 5ML 6.0 0 0 N/A N/A] [151090 ANTI SERUM A 10ML 6.0 0 0 N/A N/A] [151094 ANTI SERUM AB 10ML 6.0 0 0 N/A N/A] [151092 ANTI SERUM B 10ML 6.0 0 0 N/A N/A] [151095 ANTI SERUM D 10ML 6.0 0 0 N/A N/A] [151825 BLOOD GLUCOSE GLUCOMETER-CONTOUR 0 0 0 N/A N/A] [151829 BLOOD GLUCOSE STRIPS(50 STRIPS)-CONTOUR 12.0 360.0 0 3000.00 % N/A] [151828 BLOOD GLUCOSE STRIPS(50 STRIPS)-SURESTEP 0 360.0 0 N/A N/A]] Thanks again On Friday, January 3, 2014 9:33:42 PM UTC+3, john walker wrote: You can do something like this. https://gist.github.com/johnwalker/8243534 On Friday, January 3, 2014 12:37:07 PM UTC-5, Jeff Angle wrote: Hi guys! this has made me pull quite a load of hair new to clojure.. have a nested vector say [[salt 0 0 %deviation 00] [sugar 5 10 %deviation 5$10] [milk 1 2 %deviation 12 ] [bread] ...] where % deviation is the actual figure of evaluting the deviation between e.g 5 and 10 for sugar, I want to sort using % deviation and also filter out those with deviations of 0.

Contributors needed for Rouge (Clojure on Ruby)
I have recently moved most of my work to Clojure and Clojurescript but neither of these implementations seem suitable for non-http scripting, for which I currently use Ruby. So, you can imagine my elation when I discovered Rouge which is Clojure implemented on Ruby: https://github.com/rouge-lang/rouge The project looks fantastic but they seem to be short of contributors. My programming skills are nowhere near advanced enough to work on this myself so, please, if any of you Clojurians have proficiency in Ruby and Clojure please consider contributing. I looked at Python's Hy (hylang.org) which is an excellent project in its own right and is heavily influenced by Clojure but its taregt is generic Lisp 1 rather than Clojure. Rouge will enable Clojure to occupy the non-http scripting space without competing directly with Clojure and Clojurescript. gvim -- -- You received this message because you are subscribed to the Google Groups Clojure group.

A Clojure layer on top of Ruby means less context switching which works better for me as the Lisp mindset is very different from Ruby or Python. However, I just looked at the Rouge docs and very little seems to have been implemented so maybe it's dying.

[ANN] core.rrb-vector 0.0.10 -- vector concatenation for Clojure(Script)
Hi, I am pleased to announce the immediate availability of version 0.0.10 of core.rrb-vector, a Clojure Contrib library enabling logarithmic-time concatenation and slicing of Clojure(Script) vectors. Leiningen: [org.clojure/core.rrb-vector 0.0.10] Maven: dependency groupIdorg.clojure/groupId artifactIdcore.rrb-vector/artifactId version0.0.10/version /dependency Gradle: compile org.clojure:core.rrb-vector:0.0.10 The public API is exported by the clojure.core.rrb-vector namespace: (require '[clojure.core.rrb-vector :as fv]) Most users will only be interested in two functions: fv/catvec and fv/subvec. These can be used with regular Clojure vectors (including vectors of primitives and view vectors created with clojure.core/subvec); there is no need to construct RRB vectors by hand. (fv/catvec (fv/subvec [0 1 2] 1 2) [3 4 5]) ;= [1 3 4 5] New in this release: * Several important bug fixes; existing users should upgrade ASAP! * Stress testing using Zach Tellman's great collection-check library (which helped catch some of the aforementioned bugs); many thanks for this one, Zach! * Support for the transient API. * ClojureScript version (same API minus vector-of). * Some forgotten Java interfaces implemented for RRB vectors. * New behaviour of fv/vec (when passed a vector, reuses its tree). The repository for this project is located here: https://github.com/clojure/core.rrb-vector See the README or (doc clojure.core.rrb-vector) for additional details.

Re: Sorting Nested Vectors and filter out some
You might wish to consider a different data structure. For example, the inner objects might be better off as maps with named keys, so your lookup keys would be things like :amount rather than 5. And instead of out of band values like the string N/A you'd just omit a mapping in such cases. At the very least you may wish to consider using nil instead of N/A as an out of band value for not there. But a map would allow easily adding more data later on, as well as enable giving the lookup keys meaningful names, and would keep the existing keys stable when new ones were added. A map may also perform better if you end up with a lot of optional keys, as missing mappings don't take up space while N/A values in a vector do. As for naming integer positions using constants, such as (def amount 5), there are two weaknesses with that approach. First, inserting new values will shift all of the existing ones that are farther to the right to higher indices, so you'd have to change amount to 6 and hope you hadn't missed any direct lookups with 5 instead of amount. But if you use a map with a key of :amount, adding more keys can never move the actual amount value away from :amount. And second, you can namespace keys to avoid collisions, with :my-ns/amount and :other-ns/amount not colliding. You can namespace def'd integer constants too, with (in-ns 'my-ns) (def amount 5) and (in-ns 'other-ns) (def amount 7), but if one day you end up with a situation where two namespaces def two different things to the key 5, the namespacing isn't going to help you. Maps with named and namespaceable :keyword keys are much more robust and scalable in large (or potentially-in-the-future-large) projects and in the presence of many optional keys. With Clojure, it's strongly recommended to use maps with named keys instead of positionally-significant entries in vectors to represent structured tuples of data like you seem to have here. The robustness becomes especially significant if you save and load data and keep old data around as the application grows. If you reorder the vectors, or insert new fields before existing ones, and then read in old data, the values will end up with the wrong keys, whereas if you use maps, keywords, and edn format the values in old data can never end up reading back in with the wrong keys (as long as you never rename already-used keys for any reason, which with meaningful names and especially namespacing you should never need to do). -- -- You received this message because you are subscribed to the Google Groups Clojure group.

[ANN] data.avl 0.0.10 -- fast sorted maps and sets with log-time rank queries
Hi, I am pleased to announce the initial Clojure Contrib release of data.avl (previously known as avl.clj), a library implementing drop-in replacements for Clojure(Script)'s sorted maps and sets with faster lookups, support for the transient API (leading to unambiguously improved performance for many usage patterns) and log-time rank queries (via clojure.core/nth and clojure.data.avl/rank-of). There are two relevant trade-offs: higher memory usage (a pointer and two ints per key) and somewhat slower single updates. See below for an extended discussion and some benchmark results. For users of avl.clj 0.0.9: this release fixes a bug in rank-of and a single reflective call I missed previously. Upgrading requires no changes other than to the namespace name, which is now clojure.data.avl. The Maven artefact is now available from Maven Central; dependency information is as follows (Leiningen / Maven / Gradle): [org.clojure/data.avl 0.0.10] dependency groupIdorg.clojure/groupId artifactIddata.avl/artifactId version0.0.10/version /dependency compile org.clojure:data.avl:0.0.10 The repository for this project is located here: https://github.com/clojure/data.avl data.avl uses persistent AVL trees as the underlying data structure. AVL trees tend to be significantly shallower than red-black trees; since the built-in sorted collections use red-black trees, data.avl maps and sets offer noticeably improved expected lookup times. The trade-off here is that updates (assoc / dissoc / conj / disj) must perform more work in rebalancing the trees, so they are typically slower than with the built-ins. However, data.avl maps and sets support the transient API, which can be used to speed up long chains of updates. Thanks to this, data.avl types tend to outperform the built-ins for batch updates. One particularly important case of this type is that of the initial construction of large instances; this tends to be noticeably faster with data.avl types (on a par with the built-ins worst-case in my benchmarking so far). (Of course the time to complete all operations varies with tree structure. When comparing lookup times for nodes occupying the same positions in both trees, the built-in red-black trees have a very slight edge; see for example (get avl 0) and (get rb 0) in the benchmark results below. Updates involving identically placed nodes may be faster in either tree type depending on the overall shape of the tree; see for example (dissoc avl 131071) and (dissoc rb 131071) below, where the AVL map completes the operation twice as fast. On average, however, performance is as described above.) Besides supporting transients, data.avl types offer two additions to the sorted collection API: (require '[clojure.data.avl :as avl]) ;; nth can be used to look up the nth smallest item in a sorted ;; collection, as determined by the comparator being used: (nth (avl/sorted-set 0 2 4) 2) ;= 4 (nth (avl/sorted-set-by 0 2 4) 2) ;= 0 ;; for maps, nth returns map entry objects: (nth (avl/sorted-map 0 0 2 2 4 4) 2) ;= [4 4] ;; clojure.data.avl/rank-of can be used to query for the index of a ;; given key in a data.avl collection: (avl/rank-of (avl/sorted-set 3 4 5) 4) ;= 1 ;; if the key is not present in the collection, -1 is returned: (avl/rank-of (avl/sorted-set 3 4 5) 0) ;= -1 As mentioned above, the new functionality comes at a cost in memory consumption. To support transients, each node in a data.avl tree must carry an extra reference field -- that's one pointer per key. To support efficient rank queries, each pointer needs to carry an extra int field. Finally, another int field is used by the rebalancing algorithm itself. The library carries its own test suite used in both Clojure and ClojureScript. Additionally, the Clojure version is stress-tested with Zach Tellman's collection-check library.
