# reshape2 1.4.4
|
||
|
|
|
||
|
|
* Fix R CMD check failure in R-devel.
|
||
|
|
|
||
|
|
# Version 1.4.3
|
||
|
|
|
||
|
|
* Fix C/C++ problems causing R CMD CHECK errors.
|
||
|
|
|
||
|
|
* `melt.data.frame()` throws when encountering objects of type `POSIXlt`,
|
||
|
|
and requests a conversion to the (much saner) `POSIXct` type.
|
||
|
|
|
||
|
|
# Version 1.4.2
|
||
|
|
|
||
|
|
* Minor R CMD check fixes for CRAN.
|
||
|
|
|
||
|
|
# Version 1.4.1
|
||
|
|
|
||
|
|
* `melt.data.frame()` now properly sets the OBJECT bit on `value` variable
|
||
|
|
generated if attributes are copied (for example, when multiple POSIXct
|
||
|
|
columns are concatenated to generate the `value` variable) (#50)
|
||
|
|
|
||
|
|
* `melt.data.frame()` can melt `data.frame`s containing `list` elements as `id`
|
||
|
|
columns. (#49)
|
||
|
|
|
||
|
|
* `melt.data.frame()` no longer errors when `measure.vars` is `NULL` or empty.
|
||
|
|
(#46)
|
||
|
|
|
||
|
|
# Version 1.4
|
||
|
|
|
||
|
|
* `dcast()` and `acast()` gain a useful error message if you use `value_var`
|
||
|
|
intead of `value.var` (#16), and if `value.var` doesn't exist (#9). They
|
||
|
|
also work better with `.` in specifications like `. ~ .` or
|
||
|
|
`x + y ~ .`
|
||
|
|
|
||
|
|
* `melt.array()` creates factor variables with levels in the same order
|
||
|
|
as the original rownames (#19)
|
||
|
|
|
||
|
|
* `melt.data.frame()` gains an internal Rcpp / C++ implementation, and
|
||
|
|
is now many orders of magnitudes faster. It also preserves identical
|
||
|
|
attributes for measure variables, and now throws a warning if they are
|
||
|
|
dropped. (Thanks to Kevin Ushey)
|
||
|
|
|
||
|
|
* `melt.data.frame()` gains a `factorsAsStrings` argument that controls whether
|
||
|
|
factors are converted to character when melted as measure variables. This
|
||
|
|
is `TRUE` by default for backward compatibility.
|
||
|
|
|
||
|
|
* `melt.array()` gains a `as.is` argument which can be used to prevent
|
||
|
|
dimnames being converted with `type.convert()`
|
||
|
|
|
||
|
|
* `recast()` now returns a data frame instead of a list (#45).
|
||
|
|
|
||
|
|
# Version 1.2.2
|
||
|
|
|
||
|
|
* Fix incompatibility with plyr 1.8
|
||
|
|
|
||
|
|
* Fix evaluation bug revealed by knitr. (Fixes #18)
|
||
|
|
|
||
|
|
* Fixed a bug in `melt` where it didn't automatically get variable names
|
||
|
|
when used with tables. (Thanks to Winston Chang)
|
||
|
|
|
||
|
|
# Version 1.2.1
|
||
|
|
|
||
|
|
* Fix bug in multiple margins revealed by plyr 1.7, but caused by mis-use of
|
||
|
|
data frame subsetting.
|
||
|
|
|
||
|
|
# Version 1.2
|
||
|
|
|
||
|
|
* Fixed bug in melt where factors were converted to integers, instead of to
|
||
|
|
characters
|
||
|
|
|
||
|
|
* When the measured variable is a factor, `dcast` now converts it to a
|
||
|
|
character rather than throwing an error. `acast` still returns a factor
|
||
|
|
matrix. (Thanks to Brian Diggs.)
|
||
|
|
|
||
|
|
* `acast` is now much faster, due to fixing a very slow way of naming the
|
||
|
|
output. (Thanks to José Bartolomei Díaz for the bug report)
|
||
|
|
|
||
|
|
* `value_var` argument to `acast` and `dcast` renamed to `value.var` to be
|
||
|
|
consistent with other argument names
|
||
|
|
|
||
|
|
* Order `NA` factor levels before `(all)` when creating margins
|
||
|
|
|
||
|
|
* Corrected reshape citation.
|
||
|
|
|
||
|
|
# Version 1.1
|
||
|
|
|
||
|
|
* `melt.data.frame` no longer turns characters into factors
|
||
|
|
|
||
|
|
* All melt methods gain a `na.rm` and `value.name` arguments - these
|
||
|
|
previously were only possessed by `melt.data.frame` (Fixes #5)
