Input figure folder as global option

[nithinmkp]

Hello,
can some one help me to define input figure folder in rmarkdown as global option? I mean I have a figures folder inside the project directory where the Rmd file is stored. I can read figure if the figures are also stored in the same place. But for organisational purpose, I like the input figures like logo, titlegraphic etc inside a separate folder. I want to define this folder as input figure folder ( simmilar to using grpahicspath in latex). Is there a way?

Hello @nithinmkp,
I am not quite sure what you trying to do, but if you are willing to specify the path in your code you could do something like:

knitr::include_graphics('./myproj/images/logo.PNG',error=F)

I must confess that I have to determine the exact path by trial and error: mostly I temporarily include a getwd() statement in the code to know 'where I am'.

Hope this helps.

There are several helper to handle file path within a project. The here package can be useful to derive path from the root directory of a project

A Simpler Way to Find Your Files

You can then use knitr::include_graphics or you can then create a wrapper function to include you image by name and the path would be prepended based on a variable.

Best way to achieve all these is to define your path and helper function in a setup chunk to use in your doc. There is no knitr option I believe for input file path of image - this is usually handle by the user.

Beware of using absolute path though when generating non standalone HTML document - your HTML doc must know how to reach the image. This is why often the images are place in a folder relative to the site root. For self_contained document this would be ok though.

I let you try

That helped. Thanks a lot. I was using here but not in a proper way. But I guess it should be a feature in later versions of knitr.

Thanks
