If you are venturing into the world of data science using R, look no further! The **Laurae Advanced High Performance Data Science Toolbox** is your ultimate companion. This guide will walk you through the installation steps and shed light on its features. Let’s get started!

Step 1: Install the Required Packages

To kick things off, you need to install the required R packages. Launch R and run the following commands:

devtools::install_github("Laurae2/Laurae")

If you are running in a virtual machine and have no proxy redirection from R, use the following alternative:

devtools::install_git("git://github.com/Laurae2/Laurae.git")

If you want to install all dependencies in one shot, execute:

install.packages(c("data.table", "foreach", "doParallel", "rpart", "rpart.plot", "partykit", "ggplot2", "ggthemes", "shiny", "shinydashboard", "miniUI", "Matrix", "Rcpp", "RcppArmadillo", "mgcv", "MASS", "stringi"))

Step 2: Setting Up XGBoost and LightGBM

Before using Laurae, you need to ensure that XGBoost and LightGBM are installed. Follow these instructions for Windows users:

For XGBoost:

Clone XGBoost using Git Bash:

git clone --recursive https://github.com/dmlc/xgboost

Navigate to the directory and compile it:

cd xgboost; mkdir build; cd build; cmake ..; make

Then, install it in R:

library(devtools); install("xgboost")

For LightGBM:

Clone LightGBM as well, following the same approach:

git clone --recursive https://github.com/microsoft/LightGBM

Compile it in the same manner as XGBoost and install using R.

Step 3: Explore Laurae’s Features

Now that everything’s installed, you can dive into the functionalities of Laurae toolbox! Here are some features you can utilize:

• Supervised Learning: Includes Dynamic Boosted Trees and Cross-Validation
• Automated Machine Learning: Provides tools for feature selection and hyperparameter tuning
• Interactive Analysis: Real-time optimization of gradient and hessian functions
• Visualization: Interactive dashboards for exploratory data analysis

Troubleshooting

If you encounter any issues during the installation or while using the toolbox, here are a few tips:

• Ensure that all dependencies are installed correctly by checking the package installation logs.
• If R throws an error about missing packages (like sparsity), you can manually install it using:

devtools::install_github("Laurae2/sparsity")

• If you face strange errors on the first run, try restarting your R session.
• For any persistent issues, ensure you have internet access and restart R.
