Oracle Data Visualisation Desktop has the feature of being able to include some advanced analytics. In a previous blog post I showed you how to go about installing Oracle R Distribution on your desktop/client machine. This will allow you to make use of some of the advanced analytics features of Oracle Data Visualization Desktop.
The best way to get started with using the advanced analytics features of Oracle Data Visualization Desktop, is to ignore that (more...)
After a bit of a long wait Oracle have finally release Oracle Data Visualization for the desktop. The desktop version of this tool is only available for Windows desktops at the moment. I'm sure Oracle will be bringing out versions of other OS soon (I hope).
To get you hands on the Oracle Data Visualization to to the following OTN webpage (click on this image)
After downloading has finished, you can run the installer.
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.

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...)
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...)
Spark is an open source Apache project that provides a framework for multi stage in-memory analytics.
