R Coding $-$ Instructions $-$

The hmeq$\_$small dataset contains information on $5960$ home equity loans, including $7$ features on the characteristics of the loan.

$-$Load the hmeq$\_$small.csv data set as a data frame.

$-$Create a new data frame with the columns LOAN and VALUE

$-$standardized and saved as LOAN$\_$STAND and VALUE$\_$STAND.

$-$Create a second data frame with the columns LOAN and VALUE

$-$normalized and saved as LOAN$\_$NORM and VALUE$\_$NORM.

$-$Print the summaries of the new data frames.

The expected output is shown on screenshot, I cannot show them all but basically looks like that. I tried it twice, and it still shows errors! I need help.

The first error :
