I have been researching a bit about custom themes in RStudio.
I can inspect an element, but I am not seeing a distinction in the class structure between an error and a message and a warning...
> print("hello");
[1] "hello"
> warning("hello");
Warning message:
hello
> stop("hello");
Error: hello
MSG:
<span class="GHF-EWBBF0B">[1] "hello"
</span>
WARNING: (two spans)
<span class="GHF-EWBBP-B ace_constant ace_language">Warning message:
</span>
<span class="GHF-EWBBP-B ace_constant ace_language">hello
</span>
ERROR: (only one span)
<span class="GHF-EWBBP-B ace_constant ace_language">Error: hello
</span>
