Docker Image Build Fail

General
1

Please, I am trying to build a docker image found in an online article. The image is supposed to install just the dplyr package. This is the Dockerfile:

FROM rocker/r-ver:4.0.0
RUN install2.r --error dplyr

But when I run the command docker build --tag dplyr_image . in my terminal, I get the error message below:

C:\Users\IFEANYI\Documents\docker> docker build --tag dplyr_image .
