Rdo_reparse: 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 athere 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 <- 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)
