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.
