[Rd] generate Rd file from R file

[Romain Francois]

Hi,

Is there something similar to javadoc or doxygen for R, ie ability to 
create a first draft of an Rd file reading the comments that are in a 
script file?

For example, for the weighted.mean function in base, one could write the 
source as :

weighted.mean <- function(
x,             #@ a numeric vector containing the values whose mean is to be computed. 
w,             #@ a vector of weights the same length as |x| giving the weights to use for each element of |x|.
na.rm = FALSE  #@ a logical value indicating whether |NA |values in |x| should be stripped before the computation proceeds.
)
#e wt <- c(5,  5,  4,  1)/15
#e x <- c(3.7,3.3,3.5,2.8)
#e xm <- weighted.mean(x,wt)


and get a draft file more full than what may be created with prompt.
Of course, I do not ask for a way to not write all the information in 
one file ... but some can be shared between R and Rd
