how to get RStudio console features tab-code-completion and live help for function coding to work

RStudio IDE
1

i am completely new to R. i just installed the R and Rstudio. R version Download R-4.2.1 for Windows. I am following the INTRODUCTION TO R SEMINAR from UCLA website. I have so far installed these packages.....
install.packages("dplyr", dependencies=TRUE)
install.packages("ggplot2", dependencies=TRUE)
install.packages("rmarkdown", dependencies=TRUE)
install.packages("shiny", dependencies=TRUE)
From the guide, I am supposed to get console features tab-code-completion and live help for function but when I type there is no pop up. Can anyone help me on how to get this to work?

I am on Linux so I may not be of much help but try:
And see if
Global Options > Code > Completion

and see if
Allow automatic completions in console

and
Show help tooltip after function completions
are checked.
