|[ NORM v. 1.1 | original version ]||The Vowel Normalization and Plotting Suite|
NORM/Vowels.R Change Log
As of April 2009, we use this page to announce and document changes made to the NORM website and Vowels R package. Most posts are from Tyler - email him if you have any questions about these things (email addresses at bottom of page). Starting in November 2011, we now post changes and other announcements to the new blog.

Numerous updates have been posted to vowels.R and to NORM this weekend with the release of versions 1.1. (It may take a few days for the new vowels.R version to post to CRAN.) Many changes are small, but users should notice several improvements. The main changes are listed here:
New & fixed in vowels.R version 1.1:

There was a small bug in the ellipsis plotting function that would make ellipses fail to draw in black & white. This has been fixed on NORM and vowels version 1.0-3, which fixes the bug (and has no other changes), will be posted to CRAN shortly. It should be up and available in the next few days.
I also fixed a bug in the NORM10_stage script that was making standard deviation error bars and ellipses fail to draw when plotting vowel means with the Watt & Fabricius function. This was a problem in the staging script only and not the vowels package. (Means were being generated and stored for the normalized values before determining the standard deviations.)

I modified the NORM10_stage script (the interface between NORM's web-interface and the vowels package backend) to ignore any blank lines that may be in a user's input file. These blank lines caused various NORM functions (such as Lobanov normalization) to fail and could easily 'sneak' into the end of an input file via MS Excel.
Tyler can't think of a reason why a user would want to have a blank field for a speaker or vowel, so now uses blank entries in those two fields to determine a blank 'line'. That is, even if there is formant data in an input file line, that line will be ignored by NORM if there is no speaker and vowel specified. (Likely, NORM would have failed anyway if this was the case, but it seems better to be explicit about this...)
Blank lines are removed in the NORM10_stage script by the following code. You can use this manually, in R with the vowels package, as well.
> vowels <- vowels[vowels[,1]!="" & vowels[,2]!="",]

Thanks to Santiago Barreda (UAlberta), vowels and NORM now plot standard deviation ellipses in addition to bars. Note that the information the ellipses provide is no different than that from the standard deviation bars, but I admit this is a slightly nicer view of the data and have added the feature due to popular demand.
New options in vowels_1.0-2:
March 19, 2009
There was a minor bug in the vowels R package (and therefore NORM) that was causing Nearey1 plots to be labeled as Nearey2 and vice-versa. The processing was correct - the bug was only in the labeling of the plot (down at the bottom, where it says "Variant..."). This has now been fixed on the website and a new vowels package, version 1.0-1, is available. It will be a few days until this update posts on CRAN, but it is available now on the About NORM page.
New NORM version 1.0! Since its first release at NWAV 2007 NORM has been in beta development (version 0.9). We are happy to announce NORM version 1.0! The web-based version (where you're at) is a bit different than it used to be. In particular, you can now set custom colors, run only one normalization procedure (or alternatively more than two), download all result files with one click, generate group means, generate standard deviation bars, and more. The actual NORM processing engine is a redesigned and complete R package. If you use R, even just a little, you are urged to download the vowels R package - see the About NORM page for more information and for links to the files. If you prefer the old version of NORM (v. 0.9), or need normalization options no longer available here, you can still use the old version.
