R: Reparse an Rd object

Rdo_reparse {Rdpack} | R Documentation

## Reparse an Rd object

### Description

Reparse an Rd object.

### Usage

    Rdo_reparse(rdo)

### Arguments

`rdo` | an Rd object

### Details

`Rdo_reparse` saves `rdo` to a temporary file and parses it with `parse_Rd`. This ensures that the Rd object is a "canonical" one, since one and the same Rd file can be produced by different (but equivalent) Rd objects.

Also, the functions in this package do not attend to attribute "srcref" (and do not use it) and reparsing takes care of this. (todo: check if there is a problem if the tempfile disappears.)

### Examples

    # the following creates Rd object rdo
    dummyfun <- function(x) x
    fn <- tempfile("dummyfun", fileext="Rd")
    reprompt(dummyfun, filename=fn)
    rdo <- tools::parse_Rd(fn)

    dottext <- "further arguments to be passed on."

    rdo2 <- Rdo_append_argument(rdo, "\dots", dottext, create = TRUE)
    rdo2 <- Rdo_append_argument(rdo2, "z", "a numeric vector")

    Rdo_show(Rdo_reparse(rdo2))

    # the following does ot show the arguments. (todo: why?)
    #    (see also examples in Rdo_append_argument)
    Rdo_show(rdo2)
