In oeli: Utilities for Developing Data Science Software

oeli 0.7.0

• Improved documentation of diff_cov(), undiff_cov(), and delta().

• Improved documentation of dmvnorm() and rmvnorm(). The mean vector can now be of length 1 for convenience. The degenerate case (covariance is zero) is now supported. Also separate dimensions of Sigma can be degenerate for rmvnorm().

• Added function split_vector_at() to split a vector at specific positions.

• Allow for zero matrix in cov_to_chol().

• Added function round_data.frame() that rounds numeric columns of a data.frame.

• Added function print_data.frame() that prints a (possibly abbreviated) data.frame.

• Renamed function group_data_frame() -> group_data.frame().

• Renamed function delete_data_frame_columns() -> delete_columns_data.frame().

oeli 0.6.0

• Added function quiet() to silence expressions.

• Added functions dtnorm() and dttnorm() to calculate the density of a (two-sided) truncated normal distribution.

• Added function correlated_regressors() to simulate correlated regressor values.

• Improved documentation.

• Removed functions check_date() and find_closest_year() (too special, only needed for {fHMM} package).

oeli 0.5.2

• Added function identical_structure() to check if two objects have the identical structure.

• Fixed bug in matrix_diagonal_indices(): did not always return integer.

oeli 0.5.1

• Added function vector_occurrence() to find the positions of first or last occurrence of unique vector elements.

oeli 0.5.0

• Added function chunk_vector() to split a vector into chunks.

• Added function insert_matrix_column() to add a column to a matrix.

• Added function insert_vector_entry() to add a entry to a vector.

• Renamed basic_package_sticker() -> package_logo() and added a demo.

• Added function matrix_diagonal_indices() that returns the indices of the diagonal elements of a quadratic matrix.

• Fixed bug in check_numeric_vector(): null.ok did not work.

• Added function subsets() that generates subsets of a vector.

• Fixed bug in system_information(): do not fail if information cannot be retrieved.

oeli 0.4.1

• Removed HMM code and plot_sequence() function (both do not really fit in this package).

• Added more vignettes to illustrate use cases.

oeli 0.4.0

• Fixed bug in checks for matrices by checking for NA, NaN and infinite values.

• Increment RoxygenNote to 7.3.0.

• Added function system_information() that returns some general system level information.

• Added functions check_list_of_lists(), test_list_of_lists(), and assert_list_of_lists().

• Added functions check_numeric_vector(), test_numeric_vector(), and assert_numeric_vector().

• Fixed a bug in merge_lists(), where NULL elements got erroneously ignored.

oeli 0.3.2

• Fixed bug in function_arguments().

oeli 0.3.1

• Fixed https://github.com/RcppCore/Rcpp/issues/1287.

oeli 0.3.0

• Added function check_date() which checks if the input has the correct date format.

• Added function find_closest_year() which finds the closest year to a given date.

• Added function match_numerics() which matches the indices of two numeric vectors as good as possible (that means with the smallest possible sum of deviations).

• Added function simulate_markov_chain() which simulates a Markov chain.

• Added function sample_transition_probability_matrix() which samples a transition probability matrix.

• Added functions test_covariance_matrix(), test_correlation_matrix(), test_transition_probability_matrix(), and test_probability_vector() (which are the "test" version of the corresponding "assert" functions).

• Added argument tolerance for covariance matrix, correlation matrix, transition probability matrix, and probability vector check functions to account for machine epsilon and avoid false positives.

• Added functions ll_hmm() and simulate_hmm() to compute log-likelihood and simulate data from hidden Markov model.

• Added argument on_time_out to function timed() that defines what action to take if the evaluation time exceeded (error, warning, or silent).

• Added support to select identifier = "all" in Index object and to suppress warnings (if unknown identifiers were selected) (globally) via the $hide_warnings field.

• Added argument logical to Index object to combine multiple identifiers either with logical and or logical or.

• Added function unexpected_error() that handles an unknown error.

• Added function group_data_frame() that groups a data.frame according to the values of a column.

• Added function delete_data_frame_columns() that deletes columns of a data.frame.

• Added function renv_development_packages() that creates a file that loads development packages so that {renv} can detect and write them to the lockfile.

• Added function plot_sequence() that plots a sequence of numbers.

• Renamed Index -> Storage.

• Initialized a package website with {pkgdown} and started to add vignettes.

oeli 0.2.0

• Added function timed() which evaluates an expression and interrupts the evaluation after a defined amount of seconds.

• Added function do.call_timed() which measures the computation time of a do.call() call.

• Added function try_silent() which tries to execute an expression and returns a string with the error message if the execution failed.

• Added R6 object Index that provides a simple indexing interface for list elements.

• Modified basic_package_sticker(): Option to add brackets to package name, now scales font, the function is no longer exported.

• Added function function_body() which extracts the body of a function.

• Added function permutation() which creates all permutations of a given vector.

• Added function variable_name() which tries to determine the name of a variable passed to a function.

• Added function function_defaults() which returns the default function arguments.

• Added R6 object Dictionary that provides a simple simple key-value interface.

• Added function merge_lists() which merges lists based on their element names.

• Renamed arguments in function timed(): expr -> expression, secs -> seconds.

• Added argument units to function do.call_timed().

oeli 0.1.0

• Initial CRAN submission.
