I made a pakcage BayesianXXX in which I also made vignette by YYY.Rmd file in its path BayesianXXX/vignettes/YYY.Rmd.
I want to paste image in YYY.Rmd and to do so, the following Rmd script is required in the YYY.Rmd.

For example, If we made ZZZ.jpg in a image file in the inst directory, that is, BayesianXXX/inst/image/ZZZ.jpg, then how to specify its path in the code
