kandi X-RAY | node-rdf Summary

node-rdf is a JavaScript library typically used in Utilities, Data Manipulation applications. node-rdf has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i rdf' or download it from GitHub, npm.

This package is a set of utilities aimed at making it simple to represent RDF data. It is targeted at Node.js, but should work cross-environment. RDF can be considered a superset of typical links found on the Web: It allows a collection of directional relationships from some subject, with a relationship predicate, to some object. On the Web, normally all three are documents. In RDF, the object may also be a literal string containing data; and the subject or object may be an existential quantifier called a blank node. The NamedNode, BlankNode, and Literal objects represent the fundamental types of data that can be found in an RDF Statement. Statements are represented as Triple. RDF doesn't define any representation of a blank nodes, except for the fact it is possible to compare two blank nodes to see if they are the same. In RDF Interfaces, a bnode is uniquely represented as an instance of BlankNode. This interface optionally allows a label, this is primarily for debugging, and two instances of BlankNodes with the same label may still represent different blank nodes. The library also exposes a function to decorate the builtin ECMAScript protoypes with methods.

Up front, "1,3,4" != 1. It seems you should look to split the strings using strsplit(., ",").

One approach is to define a helper function that matches for a specific animal, then bind the columns to the original frame.

Note that some wrangling is done to get rid of whitespace to identify the unique animals to query.

We can use stri_replace_all_regex to replace your color_1 into integers together with the arithmetic operator.

Here I've stored your values into a vector color_1_convert. We can use this as the input in stri_replace_all_regex for better management of the values.

How to make a rank column in R

Asked 2022-Mar-07 at 16:19

I have a database with columns M1, M2 and M3. These M values correspond to the values obtained by each method. My idea is now to make a rank column for each of them. For M1 and M2, the rank will be from the highest value to the lowest value and M3 in reverse. I made the output table for you to see.

With your show samples, attempts; please try following awk code. Since you are opening files all together it may fail with infamous "too many files opened error" So to avoid that have all values into an array and in END block of this awk code print them one by one and I am closing them ASAP all contents are getting printed to output file.

Break Apart a String into Separate Columns R

Asked 2021-Dec-17 at 20:39

I am trying to tidy up some data that is all contained in 1 column called "game_info" as a string. This data contains college basketball upcoming game data, with the Date, Time, Team IDs, Team Names, etc. Ideally each one of those would be their own column. I have tried separating with a space delimiter, but that has not worked well since there are teams such as "Duke" with 1 part to their name, and teams with 2 to 3 parts to their name (Michigan State, South Dakota State, etc). There also teams with "-" dashes in their name.

The domains of the functions ensure consistency with all the other applications found in the RDF universe. Literal treats xsd:string as no datatype, and treats any language literal as rdf:langString. The RDF1.1 datatype is available through the Literal#datatype property. The RDF1.0 datatype, which null for plain literals and language strings, is available through Literal#type.
