In-development help for package loaded with devtools

dev_help() searches for source documentation provided in packages loaded by devtools. To improve performance, the .Rd files are parsed to create to index once, then cached. Use dev_topic_index_reset() to clear that index. You can manually retrieve the index for a local package with dev_topic_index().

Usage

dev_help(
  topic,
  dev_packages = NULL,
  stage = "render",
  type = getOption("help_type")
)

dev_topic_find(topic, dev_packages = NULL)

dev_topic_index(path = ".")

dev_topic_index_reset(pkg_name)

Arguments

topic: name of help to search for.
dev_packages: A character vector of package names to search within. If NULL, defaults to all packages loaded by devtools.
stage: at which stage ("build", "install", or "render") should \\Sexpr macros be executed? This is only important if you're using \\Sexpr macro's in your Rd files.
type: of html to produce: "html" or "text". Defaults to your default documentation type.
path: Path to package.
pkg_name: Name of package.

Examples

if (FALSE) {
library("ggplot2")
help("ggplot") # loads installed documentation for ggplot

load_all("ggplot2")
dev_help("ggplot") # loads development documentation for ggplot
}
