Package: listenv
================
Version: 0.8.0-9000 [2021-02-14]
NEW FEATURES:
* Add aperm() and t() for list-environment arrays.
* parse_env_subset() gained argument 'is_variable' to control whether or not
the inferred element named should be checked if it is a valid variable name
or not.
DEPRECATED AND DEFUNCT:
* map() is formally deprecated; use mapping() instead.
* Dropped the defunct usage of listenv(length = n), meaning it no longer gives
an error but instead produces a listenv with an element named 'length'.
Version: 0.8.0 [2019-12-05]
SIGNFICANT CHANGES:
* S3 method lengths.listenv() is no longer exported.
NEW FEATURES:
* Made several error messages more informative. The downside is that those
messages are no longer translated (because they are no longer aligned with
built-in R error messages which have translations)
BUG FIXES:
* parse_env_subset(x[1, names]) on a listenv 'x' matrix would throw error
'Error in if (any(i < 0)) { : missing value where TRUE/FALSE needed' if
one of the elements in 'names' specifies a non-existing column name.
* parse_env_subset(x[]) on a listenv 'x' would throw an error on
"Invalid subset: 'x[]'".
* parse_env_subset(x[names]) on a listenv 'x' would throw an error on
'length(x) = 2 > 1' in coercion to 'logical(1)' when length(names) > 1
and _R_CHECK_LENGTH_1_LOGIC2_=true.
* parse_env_subset(x[1,idxs]) on a listenv 'x' would throw an error on
'length(x) = 2 > 1' in coercion to 'logical(1)' with length(idxs) > 1
and _R_CHECK_LENGTH_1_LOGIC2_=true.
* parse_env_subset(x[[names]]) on a regular environment 'x' with
length(names) > 1 would not throw an error, whereas x[[names]] would.
* parse_env_subset(x[[1]]) on a regular environment 'x' would not throw
an error, whereas x[[1]] would.
Version: 0.7.0 [2018-01-21]
NEW FEATURES:
* Now it is possible to set the dimension on an empty list environment without
first resizing it with length(), e.g. x <- listenv(); dim(x) <- c(2, 3).
* Now it is possible to remove multiple elements by assigning NULL, e.g.
x[c(2:3, 10)] <- NULL and x[, "B"] <- NULL.
* Added lengths() for list environments. Requires R (>= 3.3.0).
* dim_na(x) <- dims, where 'dims' contain exactly one missing value, will
set the "missing" dimension based on the length of 'x' and the other
dimensions specified, e.g. with length(x) == 6, dim_na(x) <- c(2, NA) will
set dim(x) <- c(2, 3). This works for all types of object to which
dimensions can be assigned - not only list environments.
* Added is.matrix(), is.array(), as.vector() and as.matrix() for list
environments.
BUG FIXES:
* print() on a named, empty list environment would output an empty string.
* Removing an element from a list environment did not remove dimensions,
e.g. x$a <- NULL.
DEPRECATED AND DEFUNCT:
* Function map() has been renamed to mapping() and same for the corresponding
replacement function. The map() and map<-() functions will soon be
deprecated and eventually defunct.
* x <- listenv(length = n) is defunct; use x <- listenv(); length(x) <- n.
Version: 0.6.0 [2015-12-27]
NEW FEATURES:
* Added support for multi-dimensional subsetting of list environments
just as for list.
BUG FIXES:
* parse_env_subset(x[[idx]]) for list environment 'x' and index 'idx' claimed
x[[idx]] exists as long as idx in [1,length(x)] but it forgot to check if
element really existed, which may not be true if 'x' has been expanded.
Version: 0.5.0 [2015-10-30]
NEW FEATURES:
* Add support for assigning elements when creating list environment
similarly how to lists work, e.g. x <- listenv(a = 1, b = 2).
* length(x) <- n now expand/truncate a list environment.
* Added unlist() and all.equal() for list environments.
DEPRECATED AND DEFUNCT:
* Deprecated x <- listenv(length = n); use x <- listenv(); length(x) <- n.
BUG FIXES:
* as.listenv(x) would drop NULL elements in 'x'.
* x[idxs], x[name] <- y and x$<name> <- y would introduce NA names for
non-named list environments.
Version: 0.4.0 [2015-08-08]
NEW FEATURES:
* Added as.listenv().
* CONSISTENCY: Assigning NULL now removes element just as lists,
e.g. x$a <- NULL. To assign value NULL, do x['a'] <- list(NULL).
* Added support for subsetting with [(), which returns another
list environment, e.g. x[2:3], x[-1] and x[c(TRUE, FALSE)].
* Added [<- assignment, e.g. x['a'] <- 1 and x[2:3] <- c(3,8).
* CLEANUP: Dropped stray debug code.
Version: 0.3.0 [2015-05-23]
CODE REFACTORIZATION:
* Package no longer depends on other packages.
Version: 0.2.4 [2015-05-22]
NEW FEATURES:
* Added helper function parse_env_subset().
Version: 0.2.3 [2015-05-21]
NEW FEATURES:
* print() on listenv() handles empty and no-named listenv:s better.
Version: 0.2.2 [2015-05-20]
NEW FEATURES:
* Now listenv(length = ...) always allocates internal variables.
Version: 0.2.1 [2015-05-19]
NEW FEATURES:
* get_variable() gained argument 'mustExist'.
Version: 0.2.0 [2015-05-19]
SIGNFICANT CHANGES:
* Moved list environments from an in-house package to its own package.
Version: 0.1.4 [2015-05-02]
NEW FEATURES:
* Added print() for listenv:s.
CODE REFACTORIZATION:
* Using tempvar() of R.utils.
Version: 0.1.0 [2015-02-07]
* Created.
