Hello,
I am unable to call the describe(product$Price) function because I cannot install the “psych package”
 

1. When I use the code:install.packages(“psych”) — I get the following error:

“Warning in install.packages : dependency ‘mnormt’ is not available”
      2.  Knock-on effect, when I try  to call library( psych)— I get the following error:
“Error in library(psych) : there is no package called ‘psych’”
 
As A result I cannot use the describe(…..) function. Any guidance would be greatly appreciated, thanks!
