When you install R you also get a set of pre-compiled datasets. These are great for trying out many of the features that are available with R and all the new packages that are being produced on an almost daily basis.
The exact list of data sets available will depend on the version of R that you are using.
To get the list of available data sets in R you can run the following.
Elastic announced their Graph tool at ElastiCON 2016 (see presentation here). It’s part of the forthcoming X-Pack which bundles Graph along with other helper tools such as Shield and Marvel. Graph itself is two things; an extension of Elasticsearch’s capabilities, enabling the user to explore how items indexed in Elasticsearch are related, and a plugin for Kibana that acts as an optional front-end for this new functionality.

Our meeting will cover two topics. The main topic for the evening will be on Data Protection. We have Daragh O'Brien (MD of Castlebridge Associate) presenting on this. Daragh is also the Global Data Privacy Officer for DAMA International. He has also been invoked in contributing to (more...)
You have heard about the cloud? Right? Even the Oracle Cloud?
If you haven't, then maybe we need to look at how you can learn more about the Oracle Cloud.
Over the past while, and in the past few weeks in particular, Oracle has been advertising about how you can get a trail Oracle cloud service setup for FREE. Well it is free for one month when you set it up on the Oracle website (more...)
In this blog post I will show you the configurations that are necessary for RStudio Server to work with Oracle R Enterprise on your Oracle Database server. In theory if you have just installed ORE and then RStudio Server, everything should work, but if you encounter any issues then check out the following.
Before I get started make sure to check out my previous blog posts on installing R Studio Server. The first blog post (more...)
In a previous blog post I showed how you can install and get started with using RStudio on a server by using RStudio Server. My previous post showed how you could do that on the Oracle BigDataLite VM. On this VM everything was nicely scripted and set up for you. But when it comes to installing it on a different server, well things can be a bit different.
A very popular tool for data scientists is RStudio. This tool allows you to interactively work with your R code, view the R console, the graphs and charts you create, manage the various objects and data frames you create, as well shaving easy access to the R help documentation. Basically it is a core everyday tool.
The typical approach is to have RStudio installed on your desktop or laptop. What this really means is that (more...)
Last week we had out OUG Ireland annual conference. Traditionally it has been a 1 day conference and in the past few years we have had an extra day where we had the likes of Tom Kyte (we miss you), Maria Colgan, etc give a full day seminar.
But over the past few years a few of the committee have been constantly asked about when we would have a second day of presentations (just like (more...)
My last article talked about a maintenance and hassle free mechanism to implement security. The article moved the security architecture to roles created in EM. The next logical step is to move the roles from one environment to another because lets face it, manually creating roles is a lot of effort.
Oracle has a process to migrate the policy store from one environment to another and is described @ http://docs.oracle.com/cd/E14571_01/core.1111/e10043/addlsecfea.htm#JISEC3593
Oracle R Enterprise comes with a vast array of features that not really documented anywhere. One of these features that I've recently found useful is the ore.recode() function.
The following code illustrates how you can records the values in an existing attributes or (more specifically in this example) how you can create a new attribute based on the values in another attribute.
The data set that I'm using is the White Wine data set (more...)
There is no question that massive data is being generated in greater volumes than ever before. Along with the traditional data set, new data sources as sensors, application logs, IOT devices, and social networks are adding to data growth. Unlike traditional ETL platforms like Informatica, ODI, DataStage that are largely proprietary commercial products, the majority of Big ETL platforms are powered by open source.
With many execution engines, customers are always curious about their usage (more...)
As I wrote in my last blogpost, Gartner’s latest version of the Magic Quadrant for Business Intelligence and Analytics Platforms (#BIAMQ) caused a lot of noise in the Analytics Market. Gartner and Oracle have different views of this market. Gartner sees a difference; “between a modern BI and Analytics Platform and a traditional, IT-centric Reporting and…Read more BI & Analytics – Agile BI and / or Enterprise Reporting?
This blog talks about a hassle free mechanism of OBIEE security implementation with almost zero overhead. We will first look at the data level security implementation and then extend it to object level security.
Data Level Security: Data level security is usually implemented using database tables. These tables store the users and the filter (more...)
