In psolymos/mefa4: Multivariate Data Handling with S4 Classes and Sparse Matrices

Version 0.3-9 -- Sep 8, 2022

• Addressing Matrix 1.5-0 deprecation issue.

Version 0.3-8 -- Oct 6, 2021

• Use DOI to JSS article instead of URL.

Version 0.3-7 -- Feb 28, 2020

• stringsAsFactors = TRUE added to data.frame() calls to prepare for R-devel changes.

Version 0.3-6 -- Jul 20, 2019

• find_max and find_min are much now faster.

Version 0.3-5 -- Mar 24, 2018

• sum_by to sum a vector by grouping indices.
• Melt uses unique colnames to avoid duplicate factor levels warning.
• rBind and cBind deprecated and rbind/cbind is used (https://stat.ethz.ch/pipermail/r-devel/2018-March/075737.html), package now depends on R (>= 3.2.0).

Version 0.3-4 -- Oct 12, 2016

• New functions: '%notin%', the negation of '%in%'; reclass for reclassifying factors; redistribute for redistributing values in a matrix.
• inst/CITATION file updated.

Version 0.3-3 -- Feb 29, 2016

• nonDuplicated now uses drop=FALSE to prevent 1-column inputs to loose their dimensions.
• New function: compare_sets to compare sets.
• New function: find_max and find_min to find max/min index and value for rows of a matrix.
• pbapply is now a dependency.

Version 0.3-2 -- Nov 21, 2015

• New function: r2rmd to parse an ordinary R source file and return an Rmd file by trimming double hashes and wrapping code chunks.
• Vignette removed from package, migrated to development site on GitHub.

Version 0.3-1 -- Nov 7, 2013

• stack method for Mefa objects: column labels for @taxa tables fixed.
• New functions: pasteDate, paste0date, nameAlnum. These were added to facilitate common character operations (versioning files, cleaning up taxonomic names).

Version 0.3-0 -- Sept 25, 2013

• Spell check completed using utils:::aspell.
• Import methods pkg in namespace to satisfy R 3.0.2 checks.
• Depends: R (>= 2.14.0) because vignette directory has moved.

Version 0.2-9 -- July 11, 2013

• Xtab: 1-row/col matrices dropped dimnames -- now fixed.
• Vignette moved to vignettes from inst/doc.

Version 0.2-8 -- July 6, 2012

• mbind2: inner set is based on x+y instead of left join x. Methods for matrix and sparse matrix classes, but not for Mefa where the sum is not trivial.
• nonDuplicated gained na.rm argument to handle possible duplicates in row names.

Version 0.2-7 -- May 2, 2012

• inst/COPYING removed.
• stack method added to Mefa class.
• groupSums, groupMeans: failed when join was "inner" and both @samp and @taxa slots of the new object were NULL. Check on NULL attribute table related join type is now relaxed for object class Mefa (reported by D. Stralberg).
• mbind uses drop=TRUE to protect single column/row cases.

Version 0.2-6 -- March 19, 2012

• Rd link to Matrix:::xtabs removed (sparse=TRUE is in stats:::xtabs). Reported by Uwe Ligges.

Version 0.2-5 -- October 18, 2011

• Startup message: line break removed.

Version 0.2-4 -- August 23, 2011

• groupMeans: NA handling changed, mean is calculated as dividing by the non-NA values when collapsing.

Version 0.2-3 -- July 9, 2011

• packageStartupMessage used in zzz.R .onAttach.
• Typos fixed in vignette and help pages.
• 1x1 dim issues fixed again using drop=FALSE at many places (Mefa, <-, [, mbind).
• typo corrected in mbind for Mefa objects that left TAXAPART temp variable in result.
• @samp/@taxa table handling in mbind for Mefa objects is revised, not using default merge(..., all=TRUE).
• Xtab: lhs must be numeric.

Version 0.2-2 -- May 13, 2011

• Allowing for 0 and 1 row/col Mefa objects ('xtab<-' and '[').
• nonDuplicated finds y in data frame and patent frame first.

Version 0.2-1 -- February 14, 2011

• Melt function added to reverse side effects of Xtab.
• Docs for Melt added (Rd, tests, vignette).

Version 0.2-0 -- February 7, 2011

• First public CRAN release.

Version 0.1-2 -- January 26, 2011

• nonDuplicated function added.
• segmented Xtab output implemented as list of sparse matrices.

Version 0.1-1 -- January 25, 2011

• S4 classes working properly.
• /tests dir added to pkg tree.
• Xtab class is redundant, use dgCMatrix class instead.
• A vignette with design decisions added, it also has the performance comparison.
• mbind method for binding matrices added with a 'left join' implementation.
• Rd files added, needs proofreading.

Version 0.1-0 -- January 20, 2011

• Start development for S4 classes.
