New stuff in the gdata R package

I have moved quite some functions from my "testing/playground" R package ggmisc to the gdata package. Bellow is the relevant text from the NEWS file. Here are the links:
NEWS:
  • New function .runRUnitTestsGdata that enables run of all RUnit tests during the R CMD check as well as directly from within R.
  • Enhanced function object.size that returns the size of multiple objects. There is also a handy print method that can print size of an object in "human readable" format when options(humanReadable=TRUE) or print(x, humanReadable=TRUE).
  • New function bindData that binds two data frames into a multivariate data frame in a different way than merge.
  • New function wideByFactor that reshapes given dataset by a given factor it creates a "multivariate" data.frame.
  • New functions getYear, getMonth, getDay, getHour, getMin, and getSec for extracting the date/time parts from objects of a date/time class.
  • New function nPairs that gives the number of variable pairs in a data.frame or a matrix.

There is also a package named gdata in CRAN by Gregory Warnes (also in gregmisc bundle).

Yes Larus, that is the package I am talking about! I added some new functions to this package. However, it will probably take some time, before the latest version hits the CRAN servers.

Ok, my misunderstanding. Have to check your new functions, I use gdata functions routinely. My blog www.r-ohjelmointi.org (only in Finnish).

Thank you for providing the link for your blog. You might consider writting in english to increase the potential readership - probably majority of useRs can survive with english.
