Special packages

[chainsawriot]

We need a list of special packages removed due to moving to the core.

These are the real default

## getOption("defaultPackages")
c("datasets", "utils", "grDevices", "graphics", "stats", "methods")

These are either unqueryable or return special results

## unqueryable
c("tools", "Rgraphviz", "parallel", "stats4")
## queryable but install along with R now; currently archived; 
## if the goal is for 2015 onwards, consider them unqueryable
c("grid", "splines", "tcltk")
## listed on CRAN, but usually not installed through CRAN
## Priority packages
c("MASS", "survival", "Matrix", "lattice", "kernSmooth") ## and many more

All Ripley's recommended packages do not have a complete history on CRAN: MASS, nnet (since 2009 only)

[chainsawriot]

Another Ripley's: class that causes #38

[chainsawriot]

Prophylactically, spatial is another recommended package maintained by Ripley but without complete history on CRAN.

[chainsawriot]

"Rgraphviz" is no longer a special package, given the bioc support.

[chainsawriot]

Special packages in the early days: (‘ctest’, ‘eda’, ‘lqs’, ‘mle’, ‘modreg’, ‘mva’, ‘nls’, ‘stepfun’ and ‘ts’).

Reference: https://cran.r-project.org/doc/manuals/R-exts.html 1.3.1 S5

[chainsawriot]

eda, lqs, mle, modreg, mva, stepfun, ts can't be searched with cran_package_history.

The cause of #144 is that DescTools lists base in Depends.
