DepMap Dataset and Files

Description

Two tibbles are provided that give access to DepMap data, as shared by the Broad Institute's DepMap project on Figshare (https://figshare.com/authors/Broad_DepMap/5514062).

- The [dmsets()] function returns a tibble with DepMap datasets. Each dataset is described by its title, its unique identifier, the number of files it contains, the Figshare URL, and a 'DepMapDataset' object that contains further details of the dataset.

- The [dmfiles()] function returns a tibble with DepMap files. Each file is described by its dataset identifier, its own unique identifier, its name, size (in bytes), a download URL, md5 hash and mime type.

- Depmap data files can be downloaded with the [dmget()] function, that takes as input a tibble or data.frame of depmap files such as 'dmfiles'. Files are downloaded and automatically in the package's central cache. See [dmCache()].

Usage

DepMapDataset(id)

DepMapFiles(x)

dmFileNames(object)

dmTitle(object)

dmNumFiles(object)

dmget(dmtab, cache = dmCache())

dmfiles()

dmsets()

Arguments

id

'numeric()' with one or multiple DepMap dataset identifier(s). Note that 'id' is converted to an integer. Missing values are not permitted.

x

either an 'numeric()' that will be passed to 'DepMapDataset' or an instance (or list of) 'DepMapDataset'.

object

an instance of class 'DepMapDataset'.

dmtab

A 'tibble' or 'data.frame' containing the file to be downloaded, such as [dmfiles()], or created by [DepMapFiles()]. If is expected to contain the '"name"', '"id"' and '"dowload_url"' variables.

cache

Object of class [BiocFileCache()]. Default is to use the central 'depmap' cache returned by [dmCache()], but users can use their own cache.

Details

The 'DepMapDataset' class stores the informtion describing a depmap dataset, as stored on Figshare (articles, as it's called there). The [DepMapDataset()] constructor requires one or multiple dataset identifiers and returns one or a list of instances.

The following accessors are available: - [dmFileNames()] returns the dataset's filenames. - [dmTitle()] returns the dataset's title. - [dmNumFiles()] returns the number of files in the dataset.

(These are used to construct the main depmap dataset tibble.)

A tibble describing the files in depmap dataset can be cretated with the [DepMapFiles()] function. It either takes one or multiple dataset idenifiers, or one or a list of 'DepMapDataset' instances

The [DepMapDataset()] and [DepMapFiles()] functions are mostly used internally, to create the 'dmsets' and 'dmfiles' tibbles. If a more recent dataset is available on Figshare and not (yet) in the 'depmap' package, a user might create the depmap files table to download the files, and/or open a [GitHub issue](https://github.com/UCLouvain-CBIO/depmap) for the new data to be added by the maintainer(s).

All the information is retrieved from Figshare using their API, as described at https://docs.figshare.com.

Adding new datasets

Adding new datasets is simple. Once a new dataset (or Article, as called on Figshare) has been identified on the Broad Institute's [DepMap project on Figshare](https://figshare.com/authors/Broad_DepMap/5514062), one needs to add the dataset's URL to the 'depmapURLs' vector in ['inst/extdata/make-dmfiles.R'](https://github.com/UCLouvain-CBIO/depmap/blob/master/inst/scripts/make-dmfiles.R), and re-run the script to update the 'dmsets.rds.' and 'dmfiles.rds' files in 'inst/extdata'.

Feel free to send a GitHub pull request or open a [GitHub issue](https://github.com/UCLouvain-CBIO/depmap) for the new data to be added by the maintainer(s).
