![R][] Across all major surveys, R has clearly dominated as one of the top programming choices for data scientists. Thus, it is no wonder that knowing the important R packages can be a vital advantage in Kaggle competitions. Xavier Conort (currently Data Scientist at Data Robot) has compiled a list of 10 R packages that played a key role in getting a top 10 ranking in more than 15 Kaggle competitions (including winning a few of them).   
  
Since R is widely being used even outside the data science community (such as by statisticians, actuaries, etc.), this list of top 10 powerful R packages might help you in more ways than you might think.   
  
Here are those 10 packages particularly powerful to build winning solutions:

1.    
    Allowing the machine to capture complexity:  
    
2.  [gbm][] \[Gradient Boosting Machine\]
3.  [randomForest][] \[Random Forest\]
4.  [e1071][] \[Support Vector Machines\]  
    Taking advantage of high-cardinality categorical or text-data:  
    
5.  [glmnet][] \[Lasso and Elastic-Net Regularized Generalized Linear Models\]
6.  [tau][] \[Text Analysis Utilities\]  
    Making your code more efficient:  
    
7.  [Matrix][tau] \[Sparse and Dense Matrix Classes and Methods\]
8.  [SOAR][] \[Memory management in R by delayed assignments\]
9.  [foreach][] \[Foreach looping construct for R\]
10. [doMC][] \[Foreach parallel adaptor for the multicore package\]
11. [data.table][] \[Extension of data.frame\]

Expert Advice for Kaggle Competitions:  Use your intuition to help the machine by doing the following:

*  Always compute differences/ratios of features
 *  Always consider discarding of features that are "too good"
