ShinyItemAnalysis (version 1.4.0)

startShinyItemAnalysis: Start ShinyItemAnalysis application

Description

An interactive shiny application to run test and item analysis. By default, the function runs the application as a background process ("Jobs" tab in the "RStudio" IDE). User is then free to use the R Console for other work and to try the sample R code examples. You can still run the app the usual way in the console by specifying background = FALSE.

Usage

startShinyItemAnalysis(background = TRUE, ...)
run_app(background = TRUE, ...)

Arguments

background

logical, should the application be run as a background process (in the 'RStudio')?

...

Arguments passed on to utils::install.packages

lib

character vector giving the library directories where to install the packages. Recycled as needed. If missing, defaults to the first element of .libPaths().

repos

character vector, the base URL(s) of the repositories to use, e.g., the URL of a CRAN mirror such as "https://cloud.r-project.org". For more details on supported URL schemes see url.

Can be NULL to install from local files, directories or URLs: this will be inferred by extension from pkgs if of length one.

contriburl

URL(s) of the contrib sections of the repositories. Use this argument if your repository mirror is incomplete, e.g., because you burned only the contrib section on a CD, or only have binary packages. Overrides argument repos. Incompatible with type = "both".

method

download method, see download.file. Unused if a non-NULL available is supplied.

available

a matrix as returned by available.packages listing packages available at the repositories, or NULL when the function makes an internal call to available.packages. Incompatible with type = "both".

destdir

directory where downloaded packages are stored. If it is NULL (the default) a subdirectory downloaded_packages of the session temporary directory will be used (and the files will be deleted at the end of the session).

dependencies

logical indicating whether to also install uninstalled packages which these packages depend on/link to/import/suggest (and so on recursively). Not used if repos = NULL. Can also be a character vector, a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances").

Only supported if lib is of length one (or missing), so it is unambiguous where to install the dependent packages. If this is not the case it is ignored, with a warning.

The default, NA, means c("Depends", "Imports", "LinkingTo").

TRUE means to use c("Depends", "Imports", "LinkingTo", "Suggests") for pkgs and c("Depends", "Imports", "LinkingTo") for added dependencies: this installs all the packages needed to run pkgs, their examples, tests and vignettes (if the package author specified them correctly).

In all of these, "LinkingTo" is omitted for binary packages.

type

character, indicating the type of package to download and install. Will be "source" except on Windows and some macOS builds: see the section on ‘Binary packages’ for those.

configure.args

(Used only for source installs.) A character vector or a named list. If a character vector with no names is supplied, the elements are concatenated into a single string (separated by a space) and used as the value for the --configure-args flag in the call to R CMD INSTALL. If the character vector has names these are assumed to identify values for --configure-args for individual packages. This allows one to specify settings for an entire collection of packages which will be used if any of those packages are to be installed. (These settings can therefore be re-used and act as default settings.)

A named list can be used also to the same effect, and that allows multi-element character strings for each package which are concatenated to a single string to be used as the value for --configure-args.

configure.vars

(Used only for source installs.) Analogous to configure.args for flag --configure-vars, which is used to set environment variables for the configure run.

clean

a logical value indicating whether to add the --clean flag to the call to R CMD INSTALL. This is sometimes used to perform additional operations at the end of the package installation in addition to removing intermediate files.

Ncpus

the number of parallel processes to use for a parallel install of more than one source package. Values greater than one are supported if the make command specified by Sys.getenv("MAKE", "make") accepts argument -k -j Ncpus.

verbose

a logical indicating if some “progress report” should be given.

INSTALL_opts

an optional character vector of additional option(s) to be passed to R CMD INSTALL for a source package install. E.g., c("--html", "--no-multiarch", "--no-test-load").

Can also be a named list of character vectors to be used as additional options, with names the respective package names.

quiet

logical: if true, reduce the amount of output. This is not passed to available.packages() in case that is called, on purpose.

keep_outputs

a logical: if true, keep the outputs from installing source packages in the current working directory, with the names of the output files the package names with .out appended. Alternatively, a character string giving the directory in which to save the outputs. Ignored when installing from local files.

Value

No return value. Called for side effects.

Examples

# NOT RUN {
startShinyItemAnalysis()
startShinyItemAnalysis(background = FALSE)
