[R] [R-pkgs] pls version 1.2-0

[Bjørn-Helge Mevik and Ron Wehrens]

Version 1.2-0 of the pls package is now available on CRAN.

The pls package implements partial least squares regression (PLSR) and
principal component regression (PCR).  Features of the package include

- Several plsr algorithms: orthogonal scores, kernel pls and simpls
- Flexible cross-validation
- A formula interface, with traditional methods like predict, coef,
  plot and summary
- Functions for extraction of scores and loadings, and calculation of
  (R)MSEP and R2
- A simple multiplicative scatter correction (msc) implementation
- Functions for plotting predictions, validation statistics,
  coefficients, scores, loadings, biplots and correlation loadings.

The main changes since 1.1-0 are

- predict() now handles missing data like the `lm' method does (the
  default is to predict `NA').
- fitted() and residuals() now return NA for observations with missing
  values, if na.action is na.exclude.
- `ncomp' is now reduced when it is too large for the requested 
  cross-validation.
- Line plot parameter arguments have been added to predplotXy(), so
  one can control the properties of the target line in predplot().
- MSEP(), RMSEP(), loadings(), loadingplot() and scoreplot() are now
  generic.
