v. 0.11.1

• the algorithm for mcrpure() method has been replaced to a similar one to avoid potential issues with original patented version.

v. 0.11.0

added methods for multivariate curve resolution plus a couple of minor improvements. See the full list here.

v. 0.10.4

• fixed a bug, which led to ignoring opacity option in plots.

v. 10.0.3

• Fixed bug #85 when using y-values as data frame gave an error in PLS regression

• Fixed bug #86 and changed the way PLS limits maximum number of components to avoid problems with singular matrices. Now if PLS algorithm finds during calculations that provided number of components is too large, it gives a warning and reduces this number.

• Code refactoring and tests for preprocessing methods

v. 0.10.2

Fixed bug #82 with categorize.pls() function.

v. 0.10.1

Small improvements related to several plotting functions, plus fixed a bug with summary() for PLS2 models. See full list of changes here. This version is also available from CRAN.

v. 0.10.0

Many changes have been made in this version, but most of them are under the hood. Code has been refactored significantly in order to improve its efficiency and make future support easier. Some functionality has been re-written from the scratch. Most of the code is backward compatible, which means your old scripts should have no problem to run with this version. However, some changes are incompatible and this can lead to occasional errors and warning messages. See list with all changes here

v. 0.9.6

• fixed a bug related to wrong calculation of R2 in case of multiple response variables (PLS2)
• refactoring of regres methods
• added tests for some of the regres methods

v. 0.9.5

• better description of cross-validation settings in help text (parameter cv)
• added column R2 (coefficient of determination) to PLS summary as it is not always identical to Y cumexpvar
• better use of cex parameter for group plots (can be specified differently for each group)
• if cex is specified it will be also applied for legend items

v. 0.9.4

• fixed a bug #59 leading to wrong results when using parameter max.cov in prep.autoscale()
