How to hide code when I run program in console in R studio?

There is a way to do this, which is to source selected text from inside the RStudio document pane. You can do this via the Rstudio API. First define the following function:

run <- function() {
  eval(parse(text = rstudioapi::primary_selection(
  rstudioapi::getSourceEditorContext())$text))
}

Now in your RStudio, you can select text in your document pane like this:

And in the R console, you can do:

run()
#> [1] "I only want to see this message"

And you can see the variables have changed as expected:

x
#> [1] 10

If you wanted to, you could bind this function to a keyboard shortcut in R Studio.
