Use rxLinMod to construct the regression: The syntax is: rxLinMod(formula, data, rowSelection)

formula - a two-sided formula that specifies the variable you want to predict on the left side, and the predictor variable(s) on the right side.
data - The dataset in which you want to search for the variables in the formula.
rowSelection - a logical expression that will be used to select particular rows for analysis. Rows in which the expression is *

Remember to use summary() to return your analysis results.
