R markdown compile error:

Question

When I try to compile an Rmarkdown document to pdf, I get this error:

    Error: Functions that produce HTML output found in document targeting latex output.
Please change the output type of this document to HTML. Alternatively, you can allow
HTML output in non-HTML formats by adding this option to the YAML front-matter of
your rmarkdown file:

  always_allow_html: yes

Note however that the HTML output will not be visible in non-HTML formats.

Does anyone know what this means?

Answer 1

You need to choose what format you want to KNIT to, tried to look at mine.

Answer 2

Have you tried the following? (FROM: https://bookdown.org/yihui/bookdown/html-widgets.html)

install.packages("webshot")
webshot::install_phantomjs()

It worked for me. See also: https://github.com/rstudio/bookdown/issues/440
