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. We are using Weka 3 which so far is proving to be a pretty neat (FREE) data mining tool. To meet my goal of improving my R skills while taking this class I needed to find a way to read .arff data files from Weka into R so that I can access the data to run the assigned tasks. 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. I was curious to see if I could do it more directly.

I ran into an interesting situation the other day when trying to import some data into Excel. I had a text file with words and definitions that I needed to have in two columns in Excel, one for the word and one for the definition. The words and their definitions were separated by a hyphen (-), so I could have…
In response to my post on importing large files into Excel by first splitting them, one of my readers, JP pointed out to me that you can bypass the splitting step by using a VBA macro to do the import. As you may know, Excel has a cut off of 65,536 rows, and so if you want to import a…
If you have a large csv file that you have tried to open in Excel, you know how troublesome that can be, because Excel is limited in the number of rows and columns of data it can handle - 65,536 rows of data and 256 columns per worksheet. Truncation of rows or columns in excess of the limit is automatic…
