RHTMLForms_0.6-0.tar.gz (19 September 2012)
This package allows us to read HTML documents and obtain a description of each of the forms it contains, along with the different elements and hidden fields. We can then programmatically generate an R function that allows us or others to treat the form as if it were an R function.
The basic steps are
library(RHTMLForms)
forms = getHTMLFormDescription("http://www.itis.gov/servlet/SingleRpt/SingleRpt")
fun = createFunction(forms[[1]])
o = fun(search_value = "dog")
The package provides functionality to obtain descriptions of HTML forms and their elements. It also provides run-time functionality for invoking the form, such as validating the arguments.
