Ignore specific files in packrat search

Question

I am creating reports using R, RStudio, knitr, and packrat. I have a project folder structure similar to below:

project_folder/
    - packrat/
    - .Rprofile
    - analaysis_folder/
        - library.R
        - child.rnw
    - data_folder/
    - knitr_rnw_location/
        - file.rnw
        - .Rprofile

And have set up the .Rprofile with the appropriate lines in the main project_folder and the subdirectory of the .rnw file, according to the recommendations given in RStudio's Limitations and Caveats page.

When I run packrat::init() at the project_folder level, the packrat folder is set up. Then when I open the file.rnw the packrat library is all set up.

However, when I execute packrat::snapshot() it gives errors

Unable to tangle file knitr_rnw_location/file.rnw; cannot parse depndencies

and fails. Is there a way to tell packrat to ignore my .rnw files? All library() are called from separate .R scripts and are source() through the .rnw files. It also searches any variables declared in the knitr chunks and gives the error

Error in eval(x, envir = envir): object 'my_variable_name' not found

In the end, it does state

Snapshot written to "~/project_folder/packrat/packrat.lock"

So I can only assume that packrat::snapshot() was successful. Has anyone else run into the same issue when working with knitr and packrat?

Much appreciated,
