Perform pointblank validation testing within R Markdown documentsSource:
validate_rmd() function sets up a framework for validation testing
within specialized validation code chunks inside an R Markdown document. To
enable this functionality,
validate_rmd() should be called early within an
R Markdown document code chunk (preferably in the
setup chunk) to signal
that validation should occur within specific code chunks. The validation code
chunks require the
validate = TRUE option to be set. Using pointblank
validation functions on data in these marked code chunks will flag overall
failure if the stop threshold is exceeded anywhere. All errors are reported
in the validation code chunk after rendering the document to HTML, where a
centered status button either indicates success or the number of overall
failures. Clicking the button reveals the otherwise hidden validation
statements and their error messages (if any).
TRUE(the default), then there will be a leading summary of all validations in the rendered R Markdown document. With
FALSE, this element is not shown.
An option to log errors to a text file. By default, no logging is done but
TRUEwill write log entries to
"validation_errors.log"in the working directory. To both enable logging and to specify a file name, include a path to a log file of the desired name.
