Take code and write it as valid YAML

Source: R/yml_helpers.R

yml_code() takes R code and writes it as valid YAML to be evaluated during knitting. Note that yml_code() does not evaluate or validate the R code but only captures it to use in the YAML field. R code needs to be formatted differently when using in the params field for parameterized reports; yml_params_code will format this correctly for you.

yml_code(x)

yml_params_code(x)
