Import the bear data into r with the r command

Question

Question: Import the bear data into R with the R command br=read.table("BearsData.txt", header=T), and form a data frame consisting only of the measurements with the R commands attach(br); bd=data.frame(Head.L, Head.W, Neck.G, Chest.G, Weight). ³ The R command cor(bd) returns a matrix of the pairwise correlations of all variables. (The matrix is symmetric because r_{X, Y} = r_{Y, X}, and its diagonal elements are 1 because the correlation of a variable with itself is

1) Using this correlation matrix, which would you say are the two best single predictors of the variable Weight?
