I have put those commands together here, but I ran the install first, got the success message, then loaded the library.Īfter that I was able to load the arff data file using the read. The four characters Weka are also 'Waikato Environment for Knowledge Analysis' abbreviation. It is a tool developed by Waikato University in New Zealand using Java.
INSTALL WEKA MAC SOFTWARE
The last step was to install the RWeka package, and then load the library. As mentioned above, Weka is a software that convers data mining, machine learning and other fields. Install the RWeka package in R (or RStudio): The “non-zero exit status” was probably a result of the previous errors, and I could not figure out what if there was another possible reason for it, so I decided to keep going.ģ.
INSTALL WEKA MAC FOR MAC OS
Click here to download a disk image for Mac OS that contains a Mac application including Azul's 64-bit OpenJDK Java VM 17 for Intel Macs. Launching via the Program Menu or shortcuts will automatically use the included JVM to run Weka. I was a bit worried about all those errors but then I realized I had already installed rJava before, hence the “restorng previous…” message. This executable will install Weka in your Program Menu. Install.packages(“rJava”,type = “source”)
Ive tried re-installing it several times and also tried different versions. When I double click on the weka icon, it opens and after around 2 seconds, it closes.

I’m using RStudio here, but either way the command would be: Ask Question Asked 9 years, 10 months ago. It also reimplements many classic data mining algorithms, including C4.5 which is called J48 in WEKA. If you want to be able to change the source code for the algorithms, WEKA is a good tool to use. Relink R with the installed Java Library on OS X. Overview WEKA is a data mining suite that is open source and is available free of charge. Here is the solution I found after a lovely Sunday morning jumping from thread to the thread on the ever helpful Stack Overflow:ġ.
When I tried to install the RWeka package into RStudio (on Mac OS X) I ran into a few issues and errors mostly involving Java. I was curious to see if I could do it more directly.Īfter some research I found that there are several options, one of which is the RWeka library. The first option, which is what most of my classmates are doing, is of course is to load the data into Weka and convert it to a CSV file and then load that file into R using the read.csv() command. arff data files from Weka into R so that I can access the data to run the assigned tasks. To meet my goal of improving my R skills while taking this class I needed to find a way to read. We are using Weka 3 which so far is proving to be a pretty neat (FREE) data mining tool. I’m currently taking a data mining class, and I’m trying to do as much of the coding in the class using R for practice.
