DTSg v0.6.0

Added subset method: allows for filtering rows and/or selecting columns of a DTSg object
Added setCols method: allows for setting the values of columns of, adding columns to and/or removing columns from a DTSg object
Added [ extract operator: acts as a shortcut for the getCol method
Added examples to the documentation of the colapply method showing how to calculate moving averages with the help of the runner package instead of the rollapply method
aggregate method can benefit from data.table’s GForce optimisation now when its fun argument is provided with a character vector specifying summary functions
Greatly sped up nas method
Temporal aggregation level functions supplied to the funby argument of the colapply method are not forced to return a POSIXct timestamp any longer. They are, however, forced to return an atomic mode (the same goes for the subset method).
getCol method now is capable of also querying the .dateTime column
R6Method argument of S3WrapperGenerator now also takes a public method of an R6ClassGenerator as a function and not only as an expression
Fixed that not all missing values were made explicit after a call to the merge method despite an "explicit" na.status in some cases
Fixed that getCol method tried to query all numeric columns instead of only the first one by default
Improved vignettes and documentation
Minor internal code improvements

Added getCol method: allows for querying the values of a single column of a DTSg object
Added funby and ignoreDST arguments to colapply: allows for applying functions like cumsum to a certain temporal level
Added na.status argument to new and alter methods: allows for making missing values either "explicit" (default) or "implicit" or leaving them alone via "undecided"
Added na.status field reflecting the status of missing values
Added na.status also to the list of helper data passed on to temporal aggregation level functions
funby argument of aggregate method now also accepts a named list of functions: allows for calculating several summary statistics at once
periodicity field can now be actively set in order to change the periodicity of the time series
timezone field can now be actively set in order to convert the time zone of the series
Fixed that a DTSg object with only one timestamp accepted a missing value in its .dateTime column
Improved vignettes and documentation
Minor internal code improvements

Fixed error “Error in as.POSIXct.numeric(e) : ‘origin’ must be supplied” related to rollback in upcoming R 4.1.0
Slightly improved vignettes
Minor internal code improvements

Added memoryOverCPU argument to rollapply method: allows for preferring CPU over memory usage which makes the method more flexible in terms of resource consumption
Settings of option DTSgClone in e.g. .RProfile are now respected and not overwritten by TRUE when the package is loaded
Fixed useless coercion of POSIXct .dateTime columns to POSIXct upon object creation in case they contained at least one missing value
Switched to unit testing framework of the tinytest package instead of the testthat package
Slightly improved vignettes and documentation
Minor internal code improvements

Added resultCols and suffix arguments to colapply and rollapply methods: allows for adding return values of applied functions as new columns instead of replacing existing ones
class argument of cols method now accepts a character vector of class names
Changed default value of class argument of cols method from "all" to NULL, however, for backward compatibility "all" can still be used for the same result, but will eventually be treated as a filter for classes of type all
Added pattern and ... arguments to cols method: allows for searching column names
Switched to argument check functions of the checkmate package instead of the assertive.base, assertive.numbers, assertive.sets and assertive.types packages
Slightly improved vignettes and documentation
Minor internal code improvements

Fixed error “Unsupported type passed to argument ‘data’.” related to dygraphs in at least some previous releases of R ≤ 3.5.3

Added swallow argument to new method: allows for a more resource efficient object creation
Added drop argument to values method: allows for a resource efficient destruction of a DTSg object while preserving its values
Added class argument to values method: can be used to return the values of a DTSg object as a data.frame instead of a data.table
alter method and linked with it new and other methods are now way more resource efficient in some cases
Added timestamps field providing the total number of timestamps
print method now omits empty metadata fields
Added means to measure code coverage with the help of covr
Removed xts from suggested packages list (already comes along with dygraphs)
Slightly improved vignettes and documentation
Minor internal code improvements
