Features
deepdep package exports the following functions:
get_available_packages,get_description,get_dependencies,get_downloads,deepdep,plot_dependencies.
Those functions rely on each other and are ordered from the lowest to the highest level. We’ll describe what they exactly do and how on examples.
get_available_packages
This function lists, as the name indicates, available packages. The default behaviour is listing all CRAN packages.
t <- get_available_packages()
head(t, 20)
#> A3 AATtools ABACUS abbreviate abbyyR abc abc.data
#> "A3" "AATtools" "ABACUS" "abbreviate" "abbyyR" "abc" "abc.data"
#> ABC.RAP abcADM ABCanalysis abclass ABCoptim ABCp2 abcrf
#> "ABC.RAP" "abcADM" "ABCanalysis" "abclass" "ABCoptim" "ABCp2" "abcrf"
#> abcrlda abctools abd abdiv abe abess
#> "abcrlda" "abctools" "abd" "abdiv" "abe" "abess"However, if you want to check if package is present in a little wider
range – on CRAN or Bioconductor repositories, you simply need to set
argument bioc = TRUE. In this case function is simply
wrapper around BiocManager::available() and to use it you
need to have BiocManager package (available via CRAN)
installed.
t <- get_available_packages(bioc = TRUE)
#> 'getOption("repos")' replaces Bioconductor standard repositories, see '?repositories' for details
#>
#> replacement repositories:
#> CRAN: https://cran.rstudio.com/
head(t, 20)
#> [1] "A3" "a4" "a4Base" "a4Classif" "a4Core" "a4Preproc" "a4Reporting"
#> [8] "AATtools" "ABACUS" "ABarray" "abbreviate" "abbyyR" "abc" "abc.data"
#> [15] "ABC.RAP" "abcADM" "ABCanalysis" "abclass" "ABCoptim" "ABCp2"Another possibility is checking what packages are installed – you do
it by adding local = TRUE parameter.
t <- get_available_packages(local = TRUE)
head(t, 20)
#> [1] "abind" "agricolae" "aigoracomponents" "aigoraML" "aigoraOpen"

get_description
When you know, that given package is available, you may want to obtain DESCRIPTION of this package, at least the most essential parts of it, especially dependencies. You can do it by calling:
get_description("DALEXtra")
#> DALEXtra: Extension for 'DALEX' Package
#> Maintainer: Szymon Maksymiuk <sz.maksymiuk@gmail.com>
#> Description:
#> Provides wrapper of various machine learning models.
#> In applied machine learning, there
#> is a strong belief that we need to strike a balance
#> between interpretability and accuracy.
#> However, in field of the interpretable machine learning,
#> there are more and more new ideas for explaining black-box models,
#> that are implemented in 'R'.
#> 'DALEXtra' creates 'DALEX' Biecek (2018) <arXiv:1806.08915> explainer for many type of models
#> including those created using 'python' 'scikit-learn' and 'keras' libraries, and 'java' 'h2o' library.
#> Important part of the package is Champion-Challenger analysis and innovative approach
#> to model performance across subsets of test data presented in Funnel Plot.
#> Depends: R DALEX
#> Imports: reticulate ggplot2
#> LinkingTo:
#> Suggests: auditor gbm ggrepel h2o iml ingredients lime localModel mlr mlr3 ranger recipes rmarkdown rpart stacks xgboost testthat tidymodels
#> Enhances:
#> Scrap date: 2022-06-14 08:08:41Again, you can pass bioc = TRUE if you want to check for
this package in Bioconductor repository. Notice that if package is not
found there, it will be searched for on CRAN. The reason behind this
type of behaviour is the fact that packages present on Bioconductor are
updated more often than on CRAN and not all of them are present here.
Option local = TRUE for only installed packages is also
possible. If a package is not available in a given source, the function
will return NULL value:
get_description("a4")
#> NULL
get_description("a4", bioc = TRUE)
#> a4: Automated Affymetrix Array Analysis Umbrella Package
#> Maintainer: Laure Cougnaud <laure.cougnaud@openanalytics.eu>
#> Description:
#> Umbrella package is available for the entire Automated Affymetrix Array Analysis suite of package.
#> Depends: a4Base a4Preproc a4Classif a4Core a4Reporting
#> Imports:
#> LinkingTo:
#> Suggests: MLP nlcv ALL Cairo Rgraphviz GOstats
#> Enhances:
#> Scrap date:Result of this function is also cached (for more details, see Caching section of this vignette).
get_downloads
This package allows you obtaining information on how many times specified package was downloaded. However, it works only with CRAN packages.
get_downloads("ggplot2")
#> x
#> last_day 58986
#> last_week 588212
#> last_month 2421187
#> last_quarter 7283366
#> last_half 15698538
#> grand_total 106188432Results of this function is not cached.
get_dependencies
After parsing description file, you can now create a
data.frame which will describe dependencies between given
package and others. You do it by using this function:
get_dependencies("ggplot2")

get_available_packages and get_description,
here you can also use bioc = TRUE or
local = TRUE and again, in case the package is not
available, the result will be NULL. Here you have another
options to set.
The first one is parameter downloads – should number of
downloads of packages be included? It uses get_downloads
and works only with CRAN packages.
Another, more important parameter is dependency_type.
You can specify how detailed should be list of dependencies. Default
value is "strong", which is a shorthand for
c("Depends", "Imports", "LinkingTo"), but you can chose any
combination of those and additionally
"Suggests", "Enhances".
get_dependencies("ggplot2", downloads = FALSE, dependency_type = c("Imports", "Suggests", "Enhances"))

deepdep
The main function of the package – it is simply wrapper around
get_dependencies, that allows you getting not only
dependencies, but also dependencies of the dependencies iteratively!
(Now you know, why we called it deepdep).
Parameters are the same as in get_dependencies, but
additionally you can specify depth parameter, which
describes how many iterations it function should perform. If
depth equals 1, it’s simply the same as calling
get_dependencies.

As famous quote says,
A picture is worth more than a thousand words.
That’s why we have plot_dependencies function. It allows
visualizing easily what are dependencies of specified package.
The function is generic, and currently supports two types of object –
you can pass a deepdep object, result of the calling the
deepdep function or just type name of the package. With the
latter option you can also pass arguments to
get_dependencies as additional parameters.
In each of the plots you can see one package name in the centre and two circles of packages gathered around them. These are dependencies of the first and second level.
Default plot type is circular, as you can see on the examples
presented above. However, you can set plot_type parameter
to tree.
Not all dependencies are plotted. To increase readability, dependencies on the same level are hidden, but you can change this behaviour
You can also make use of numbers of downloads you obtained. There is an option to add labels to only certain percentage of most downloaded packages among those that are about to be plotted. This is meant to increase readability of the plot.
Finally, returned object is a ggplot object, so you can
easily manipulate them with syntax known from ggplot2
package. We also use ggraph enhancement for plotting
graphs.
plot_dependencies(dd) +
ggplot2::scale_fill_manual(values = c("#462CF8", "#F23A90", "#AF1023")) +
ggraph::scale_edge_color_manual(values = "black")
#> Scale for fill is already present.
#> Adding another scale for fill, which will replace the existing scale.
