Xpose / News: Recent posts

A new version of Xpose has been released. Lots of new plots and features. Note that, installation of Xpose has been simplified; it is now available through the Comprehensive R Archive Network (CRAN). See http://xpose.sourceforge.net/docs_install.php for more details.

* Changed the behaviour of xpose.multiple.plot.default. Now
multiple plots are returned as objects just like single plots are
(no automatic printing from the function that created the plot
list). This is accomplished by defining a new class -
xpose.multiple.plots - and corresponding print and show methods for
that class.
* Updated xpose.VPC, xpose.VPC.categorical and xpose.VPC.both to
handle the new format of PsN vpc_results.csv
files.
* see changelog for more details

We have updated xpose for NONMEM 7 as well as added functions for odd type (categorical, TTE, count) plots including VPCs.

This release makes Xpose 4 compatible with R 2.8.0. We have updated the method for opening graphical devices to be consistent with the new methods used in R version 2.8.0. Other changes are considered minor. Please see the change-log for more information.

A minor fix. In the previous release, in compute.cwres(), a debugging flag had been left in the file resulting in R going into debugging mode when this function was called. This has been fixed in this release.

Xpose version 4.0.2 is now available. This is a maintenance release for xpose with improved functionality for xpose.VPC() and some minor bug fixes. To find out more please read the release notes on the download page.

Our first non-preview release! This version of Xpose incorporates visual and numerical predictive check capabilities, in concert with Perl-speaks-NONMEM (http://psn.sf.net). For more information type, at the R command line:

?npc.coverage
?xpose.VPC

A quick bug fix for titles of plots with multiple graphs. Now they can be specified to be anything the user desires. Just use the 'main' argument at the command line.

A new release of xpose is now available. This release changes the default way tables should be created so that xpose can calculate the CWRES, see the help page for 'compute.cwres' for more information. This release also updates the 'mirror' option, all plots in xpose can now handle the mirror option to create simulated comparison plots.

Xpose 4 release 5 update 1 is now available. This release fixes some small bugs and updates the methods used in the mirror functionality of the plots available in Xpose.

Xpose 4 preview release 5 is now available! This release fixes a bug found in the CWRES calculation, that affected results if the ID's in a NONMEM dataset were not in order (i.e. if ID=2 was before ID=1). The CWRES will still have a problem if two separate individuals have the same ID value in a NONMEM dataset (but this, we believe, is a rare occurance). A new plot of the CWRES and WRES vs. PRED is also included in this release.

The latest preview release of Xpose 4 is now available. This latest version has an improved run summary (type '?runsum.new' at the command line) and fixes bugs from the previous release.

Fixes the previous release of update 7 which mistakenly contained old .zip/.gz arichives. This new release now does all that release 7 claims to do!

Update 7 (Update 6 was an internal release only) adds functions for drawing tables using the graphics device, for displaying IWRES and ETA distributions, and for printing multiple plots on a single page. In addition, we have added fixes for the popular run summary function, correcting issues with reading in parameter estimates amongst other things, and for the GAM-related plots, which were broken in Update 5.... read more

Update 5 to PR3 fixes a slew of annoying little issues. This is an essential update - get it in the usual place.

Update 4 for Xpose 4.0 PR3 has been released, fixing a number of issues relating to file devices. Piping plots to non-screen devices (e.g. pdf, postscript, jpeg, etc) should now work flawlessly. See the FAQ on how to do this in practice, and download from the usual place!

Online documentation, based on the R manual files for Xpose, is now available from the Documentation page. It lists every function in each of the four packages, and provides details of all relevant arguments. By popular demand!

The same information is available from the R console, and may be accessed using the question mark function (e.g. ?dv.vs.pred).

A somewhat minor update, correcting a bug in subsets with the individual plots function (ind.plots).

Update 2 for PR3 has just been released, containing such new features as preliminary Linux support, scatterplot matrices, completely accurate and complete online documentation, and numerous bugfixes. Xpose 4.0 PR3-2 is available on the Downloads page, as usual.

Unsurprisingly, there were a couple of bugs in PR3, including some problems with CWRES calculations, and a couple of minor issues with the histogram plots. These are now all fixed and rolled up into PR3 Update 1.

Now you can compute CWRES values in Xpose! Take a look at the R online help ('?compute.cwres') for a rundown on how.

Well, it's not a holiday - unless you're in Sweden, where it's the day before National Day - but we're releasing Xpose 4.0 PR3 anyway. Codenamed "Midnight Sun", because it doesn't get very dark in Uppsala around this time of year, this version reintroduces the GAM, fixes most outstanding bugs, and most excitingly, adds conditional weighted residual (CWRES) functionality.

Update 1 for PR2 has been released. Support for changing data item labels from the classic menu system has been added.

Another holiday, another Xpose release! Just in time for Easter - well, if you're Greek Orthodox, anyway, and if your Easter Bunny has time management skills similar to Alice in Wonderland's White Rabbit - Xpose 4.0 Preview Release 2, codenamed "Easter Bunny", has arrived. New in this version: variable and graphics preferences, support fro saving and loading of graphical themes, data summaries, numerous fixes, automatic installation from .zip from within R, and many other new features.... read more

Not really so much of an update as a slight modification of the individual plots, and a source release for those of you brave enough to build your own software! You may find the files in the usual place, i.e. follow the download links to SourceForge.
