Repeated measures data require a different analysis procedure than our typical one-way ANOVA and subsequently follow a different R process. This tutorial will demonstrate how to conduct one-way repeated measures ANOVA in R using the Anova(mod, idata, i...
Admittedly I am not the best R coder, and I certainly have a lot to learn, but the code at the link below should provide you with an example of how easy it is to create a very (repeat: very) basic web crawler in R. If you wanted to do this in SPSS, and I 
When an interaction is present in a two-way ANOVA, we typically choose to ignore the main effects and elect to investigate the simple main effects when making pairwise comparisons. This tutorial will demonstrate how to conduct pairwise comparisons when...
By extending our one-way ANOVA procedure, we can test the pairwise comparisons between the levels of several independent variables. This tutorial will demonstrate how to conduct pairwise comparisons in a two-way ANOVA.Tutorial FilesBefore we begin, you...
When we have more than two groups in a one-way ANOVA, we typically want to statistically assess the differences between each group. Whereas a one-way omnibus ANOVA assesses whether a significant difference exists at all amongst the groups, pairwise com...
As with the one-way case, testing the omnibus hypothesis via two-way ANOVA is simple process in R. This tutorial will explore how R can be used to perform a two-way ANOVA to test the difference between two (or more) group means.Tutorial FilesBefore we ...
I should have probably figured this out a long time ago, but as I get deeper into programming with R, I am finding the need to remove all rows from a dataframe. I was making this alot harder than it had to be. your.df<- your.df Replace your.df with, your dataframe and you are good 
That is the second tutorial of Rapidminer and R extension for Trading and the first in Video. In the last example the ROC obtained is not as good as it should be to make money in this business, To improve the strategy we will try to optimize the tradin...
RapidMiner + R is an advanced tool that can be used to analyze trading strategies, In order to check its power I made a simple example using an algorithm based on a support vector machine for predicting the next day's price and based on it I generated ...
