Skip to contents

Add content to the element of an Rd object or fragment at a given position.

Usage

append_to_Rd_list(rdo, x, pos)

Arguments

rdo

an Rd object

x

the content to append, an Rd object or a list of Rd objects.

pos

position at which to append x, typically an integer but may be anything accepted by the operator "[[".

Details

The element of rdo at position pos is replaced by its concatenation with x. The result keeps the "Rd_tag" of rdo[[pos]].

Argument pos may specify a position at any depth of the Rd object.

This function is relatively low level and is mainly for use by other functions.

Value

the modified rdo object

Examples

#rdoseq <- utils:::.getHelpFile(help("seq"))
rdoseq <- Rdo_fetch("seq", "base")
iusage <- which(tools:::RdTags(rdoseq) == "\\usage")
iusage
#> [1] 10
attr(rdoseq[[iusage]], "Rd_tag")
#> [1] "\\usage"

## append a new line after the last usage line
rdoseq2 <- append_to_Rd_list(rdoseq, list(Rdo_newline()), iusage)

## Suppose that we wish to describe the function 'sequence' in the same Rd file.
## We append an usage statement for 'sequence()', without worrying about its
## actual signature.
rdoseq2 <- append_to_Rd_list(rdoseq2, list(Rdo_Rcode("sequence()")), iusage)
Rdo_show(rdoseq2)

## the two operations can be done in one step
rdoseq3 <- append_to_Rd_list(rdoseq, list(Rdo_newline(), Rdo_Rcode("sequence()")), iusage)
Rdo_show(rdoseq3)

## now run reprompt() to update rdoseq3, namely:
##    (1) it corrects the signature of 'sequence' in section \usage.
##    (2) reports new argument "nvec"
##    (3) inserts \item for the new argument(s) in section \arguments.
