‘Spectrum()’ and ‘aggregate_imp()’ no longer rely on the defunct
function ‘dplyr::id()’ (@DavisVaughan, #2).
kerntools 1.2.0
Major changes
Two new kernels, ‘Aitchison()’ and ‘cLinear()’, for compositional
data.
A new kernel, ‘Chi2()’, for computing the chi-squared kernel for
bags-of-words.
New function, ‘aggregate_imp()’, that aggregates a table of features
following a user-defined grouping criterion.
Minor improvements and bug
fixes
‘plotImp()’ now throws an error when the user requests more features
than the actual number of features present in x. Also, problems when
displaying the correct xlim are fixed.
‘heatK()’ allows the user to input a legend title.
‘KTA()’ now only accepts binary variables for its parameter
‘y’.
kerntools 1.1.0
New vignettes explaining in depth kernel PCA and the kernel
functions implemented in this package.
New example dataset (‘soil’) that contains bacterial
counts.
kerntools 1.0.2
Fixed errors that arose during CRAN Package Check when using
alternative BLAS/LAPACK implementations.
kerntools 1.0.1
Fixed some typos in the DESCRIPTION file and the ‘Acc()’
function.
