%description
Quantitative Structure-Activity Relationship (QSAR) modeling is a valuable
tool in computational chemistry and drug design, where it aims to predict
the activity or property of chemical compounds based on their molecular
structure. In this vignette, we present the 'rQSAR' package, which
provides functions for variable selection and QSAR modeling using Multiple
Linear Regression (MLR), Partial Least Squares (PLS), and Random Forest
algorithms.
