I have a problem with output of an R code in beamer_presentation with Markdown. One of my r code apart from a plot returns something like this:

## $title
## list()
## attr(,"class")
## [1] "waiver"##
...

My r code options are: {r, echo=FALSE, warning=FALSE, fig.height = 3, fig.width = 3}

I've tried to remove it with a cache and message options. Other codes works normal so I'm really confused. I will be very grateful for any help.

You really should do so from now on to get good help quickly.

    taking a punt... have you forgotten to use `+` to connect the rest of your ggplot code to a line of code defining a title i,e, you just have `labs()` or `ggtitle()` but not `+ labs()` – user20650 Jun 02 '20 at 10:44
