A new version of analogue was pushed to CRAN a few days ago. This release was precipitated by the release of R 2.10.0, and features the following key additions and fixes:

* WA models can now make full use of tolerance down-weighting, including cross validation, and all WA models benefit from key computations being conducted in faster C code;

* tran: now has a formula method and includes new transformations; power, 4th root and log-ratio transformations. tran() now also provides row (sample) centring;

* roc: For large problems the calculation of AUC and its standard error could overflow the largest number R currently handles. roc() now has two new arguments, 'thin' and 'max.len', which allow the number of points on the ROC curve to be thinned to a smaller number, which should allow the computations to be performed.

* Stratiplot: can now reverse the y-axis limits and has option to sort the variables plotted according to their weight average for the 'y' variable (to emphasis compositional change in 'y') or a further supplied variable.

* join: the value used to replace NAs can now be set by the user, and the inner and left joins as well as the default outer join.

See the ChangeLog for more detailed information.
