Insstalling packages Error

I was trying to do a ztest. And found out R require a BDSA library package. When I tried using install.packages("BDSA") & library(BDSA)

Following error pops up.

Warning in install.packages :
package ‘BDSA’ is not available (for R version 3.6.1)

Tried the following steps to upgrade R too.

  1. Install and load installr : install.packages("installr") and library(installr)
  2. Call updateR() function. ...
  3. From within RStudio , go to Help > Check for Updates to install newer version of RStudio (if available, optional).

Kindly help me out!!!

Thank you!!!

I think you are just making a typo and the package you actually want is called BSDA
