Dear Yihui,
Thank you for the valuable questions.
sample_analysis is a "tibble" while
configuration is an "R6" class.
But I also have parametrized reports where I pass R reference classes
as arguments.
This is the Rmd yaml params part corresponding to the error message.
params:
configuration: !r get(data(skylineconfig))
data: !r get(data(sample_analysis))
Might the R6 class which I pass to configuration the source of the
problem here? I have heard somewhere that R6 uses environments to
implemented some features.
There is also a further problem I am encountering reproducible when
running devtools::install() or R CMD INSTALL
** installing vignettes
'tr_srm_summary.Rmd' using 'UTF-8'
Warning in data(skylineconfig) : data set 'skylineconfig' not found
Error in get(data(skylineconfig)) : object 'skylineconfig' not found
You likely need to specify the package name, e.g.
data("skylineconfig", package = "yourpackage")
Also see my suggestion to use quote() to delay evaluation:
params:
configuration: !r quote(get(data(sample_analysis)))
in the YAML will set configuration to the expression needed to get the
environment;
eval(params$configuration)
