ai_ask() function that displays a help page with the results from a question, ai_explain_term() to explain terminology, ai_explain_function() to create a simplified help page for an R function, ai_explain_code() to explain how a (short piece of) code works and ai_explain_error() which details error message given the code and the error it generates. Credentials are handled through API keys.Packages {tabularise} and {inferit} added.
Default for silent= argument of SciViews::R is now TRUE
The parameter threads.percent= argument is added to SciViews::R. It defines the percentage of threads that both {data.table} and {collapse} can use for their parallelized code.
Topics are now implemented in SciViews::R. One can specify, for instance, SciViews::R("model") to load more packages related to modeling with regressions. Current topics are 'infer', 'model', 'explore', 'ml', 'ts' and 'spatial'. It is possible to specify more than one topic.
The new function sciviews_packages_topics() lists all packages required for each topic.
SciViews::R has now a new argument lang= to specify the default language to use. Hence, SciViews::R(lang = "fr") will set French as the default language used by functions like data.io::read(), or for plot axes labels or title.
{tidyverse} is not loaded any more, but a selected series of tidyverse packages useful for SciViews::R.
SciViews::R has now an argument to set which is the default data frame object to use (data.frame, tibble, or data.table with as_dtx=). The default value is data.table. In all cases, a message is printed to clearly indicate which is the default.
Startup messages with SciViews::R are now more complete regarding functions conflicts (it does not use tidyverse_conflicts() any more).
Restrict {cli} and {crayon} imports to avoid a conflict with num_ansi_colors() that is defined in both packages when called from ansi::num_colors().
{rmarkdown} dependency added to suggests field for the vignettes.
panel_smooth() is reworked to avoid a bug in the documentation. It still calls graphics::panel.smooth() internally.
A 'pkgdown' web site is added.
SciViews::R.SciViews::R is the instruction to use to load all required packages to install a complete SciViews::R dialect (R base + tidyverse + ...).lg(), lb() and ln1p().'correlation' objects are now 'Correlation' to avoid clash with 'correlation' objects from 'nlme' package.
Doc rewritten in Roxygen2 and R Markdown (keeping only pca vignette). More strict importFrom() in particular from 'ellipse' package.
Elimination of files.R, character.R & graphics.R (experimental code that never reached CRAN).
Code rewritten to match tidyverse style guide. Functions that are not snake case like rwb.colors() or panel.hist() now are seconded by they equivalent rwb_colors() or panel_hist().
p() is renamed p0() to avoid a clash with p() in the 'ascii' package.
rx objects are renamed regex and perl objects are renamed pcre.
fileSymlink() is renamed fileSymLink() for correct camel case support.
path object is renamed filePath to avoid a clash with a path object in 'grid' package. Related function path(), is.path(), as.path() are renamed accordingly filePath(), is.filePath() and as.filePath(). The print() method is also adapted.
warnAssignWithEqualSign, warnPartialMatchArgs, warnPartialMatchAttr and warnPartialMatchDollar in options() are now initialized to FALSE if they are not defined yet there.
Import from data.table is eliminated. For now, @:= is the same as @<-.
Temporary objects are now saved in SciViews:TempEnv instead of TempEnv.
Improvements to activate warnings regarding possible R traps: if warnPartialMatchArgs, warnPartialMatchAttr, or warnPartialMatchDollar options are not defined yet, they are set to TRUE when the packages loads.
For a similar purpose, we would like to avoid using = in place of <- for assignation. So, the = function is redefined to display a warning when it is used and when warnAssignWithEqualSign option is set to TRUE (by default). The warning message also suggests it may be == erroneously written =.
Many functions are added with more coherent names for graphics.
Several changes in character.R.
Added the rwg.colors() function.
Small corrections in man pages.
Partial argument matching for all(.names) in names(). Fixed.
Added further (misc) functions.
New syntax using x@attr for attributes, plus := for replacement by reference inspired from data.table package, which SciViews now imports too.
hsv() function disappears in R 2.14.0. As a consequence, the same gamma argument is dropped from rwb.colors(), ryg.colors() and cwm.colors().svd.pca() subfunction of pcomp.default() was corrected.lb() function as a synonym of log2().
