Other Changes

File Comment
  • Handle special case of cvi being single-valued in ann. This occurs if using CV with nsplits=2.
  • Fix for saving classes from plot.
  • Did not plot results for the uppermost model (highest RMSECV) in case when using pcolor (number of variables > 100).
  • Add tsqlim to model, for confidence level specified in options.
  • Fix calculation of X residuals in case of using PCR or PLS local model LWR. This affects calculated Q limit (model.detail.reslim{1}).
  • r2calc was too aggressive in trying to match x and y dimensions by transposing one, unintentionally applied when x and y are square and have same size.
