Modify pointblank validation testing options within R Markdown documents

Using pointblank in an R Markdown workflow is enabled by default once the pointblank library is loaded. The framework allows for validation testing within specialized validation code chunks where the validate = TRUE option is 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 green or red status buttons indicate whether all validations succeeded or failures occurred. Clicking any such button reveals the otherwise hidden validation statements and their error messages (if any). While the framework for such testing is set up by default, the validate_rmd() function offers an opportunity to set UI and logging options.

validate_rmd(summary = TRUE, log_to_file = NULL)

Arguments

summary	If 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.
log_to_file	An option to log errors to a text file. By default, no logging is done but TRUE will 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.
