rlist 0.4 (2015-01-24)
- New features
- Include a dataset 'nyweather' scraped from [OpenWeatherMap](https://openweathermap.org/) (#2)
- 'list.load' now supports text-based progress bar when 'progress = TRUE' which is by default
enabled if over 5 files are to be loaded. (#92)
- New function 'list.names' gives a list or vector names by mapping.
- New functions 'list.first' and 'list.last' find the first or last list element that meets a
given condition.
- New function 'list.unzip' to transform a list of elements with similar structure into a
list of decoupled fields.
- Improvements
- Add error handling in several edge cases. (#18)
- 'list.group' now supports grouping by multi-key which produces multi-level list. (#69)
- 'list.load' now supports loading from multiple filenames given in character vector. (#74)
- 'list.load' is now able to guess the file format even if the file type is not specified. (#76)
- 'list.maps' now allows the usage of '..1', '..2', etc. to refer to unnamed arguments. (#80)
- 'list.load' now supports merging and ungrouping as means to aggregating loaded results. (#82)
- 'list.stack' now uses 'data.table::setDF' to convert 'data.table' to 'data.frame' if
'data.table = FALSE', which is done by reference and thus has higher performance.
- Bug fixes
- 'list.search' now takes 'n' as the number of returned vector rather than that of the
elements in all returned vectors, and is now able to jump out when the result set reaches
given capacity. (#47, #84)
- Fix how 'list.table' deals with 'NULL' values. (#73)
- Fix how wrapper functions deal with default arguments. (#75)
- Fix the dynamic scoping issues in 'list.table'. (#86)
- 'list.all' and 'list.any' behave the same as 'all' and 'any' respectively when the input is empty. (#87)
- One-sided formula does not result in error now. (#89)
- 'list.flatten' now preserves names as specified. (#90)
- Fix incorrect processing for fallback in 'list.findi'. (#91)
- Fix the implementation in 'list.group' working with multi-key. (#93)
- Fix incorrect ordering if some entries are multi-valued vectors and others and single-
valued. If 'list.order' and 'list.sort' encounter such situation, they now report
error rather than silently produced unreliable results. (#94)
- Fix inconsistencies in 'list.all', 'list.any', 'list.first' and 'list.last'.
- Deprecation
- 'equal()' is removed and related packages are now suggested rather than imported. (#70)
- 'summary.list()' is deprecated. (#70)
- No longer interprets 'x -> f(x)' as a form a lambda expression. Use 'x ~ f(x)' instead. (#54)
- 'desc(x)' is no longer supported in 'list.sort' and 'list.order'. Use '-x' or '(x)' instead. (#66)
rlist 0.3 (2014-08-07)
API Break: 'list.search' now evaluates expression recursively in a list and supports lambda expression
Add 'equal()' function for logical and fuzzy filtering and searching which supports exact equality, atomic equality, inclusion, pattern matching, string-distance tolerance
Add 'List()' to provide an environment in which most list functions are defined for light-weight chaining that does not rely on external operators
rlist 0.2.5 (2014-08-01)
Add 'list.apply' which is a wrapper function of lapply
Add 'list.search' that searches a list recursively
Add exact search functions: 'equal', 'unequal', 'unidentical', 'include', and 'exclude
Add fuzzy search functions: 'like' and 'unlike' based on stringdist package
Enhance 'list.clean' which now supports recursive cleaning
rlist 0.2.4 (2014-07-26)
Add 'list.common' that returns the common cases of all list member by expression
rlist 0.2.3 (2014-07-18)
Improve performance (#26, #27
Add 'list.flatten' that flattens a nested list to one-level
rlist 0.2.2 (2014-07-11)
Add 'list.stack' that binds list members to a data.frame
Add 'list.zip' that combines multiple lists element-wisely
Add 'list.maps' that performs mapping over multiple lists
