NEWS for package rchemo

Version 0.0-18

  • Bug fixed in Pca.summary (the bug appeared between 0.0-16 and 0.0-17).

Version 0.0-17

  • Function sampclas has been renamed to sampcla and modified.

  • Correction of help page of plslda

Version 0.0-16

  • Argument rob in functions scordis and odis has been set to TRUE.

Version 0.0-15

  • Internal modification in all the LWPLS functions: add a stabilization in computed weights

Version 0.0-14

  • Correction of a small bug in checkdupl

  • Argument cri has been added in all the LWPLS functions.

Version 0.0-13

  • Functions using RBF, polynomial and sigmoid kernels

    • parameter "sigma" has been replaced by parameter "gamma" (= .5 * 1 / sigma^2)
    • parameter "scale" has been renamed "gamma"
    • parameter "offset" has been renamed "coef0"

Version 0.0-12

  • Function gaprm has been renamed to rmgap.

  • Bug correction:

    • xfit returned non-correct values for PLS models, which had impact on function odis. The bug is fixed now. It was created during the transfer from rnirs to rchemo (odis in rnirs returns correct values).
