fCWTr 0.2.9000

• fcwt():

  • fix a bug where fcwt(..., n_freqs = 1, ...) leads to a faulty data representation.

  • add freq_scale argument to choose between a linear or logarithmic frequency scale.

  • allow (and prefer) sample_freq, freq_begin, freq_end arguments to be passed as a dimensionful quantities, via u().

  • minor argument name changes.

  • add new argument y_sample_freq which allows to specify the sampling rate of the output signal.

  • add meaningful default values for most of the arguments.

• fcwt_batch():

  • allow (and prefer) sample_freq, freq_begin, freq_end and time_resolution arguments to be passed as a dimensionful quantities, via u().

  • in some cases, the averaging procedure together with the batching could lead to accidentally dropped or duplicated time slices: the mechanism has been overhauled, every slice should be perfectly aligned now, even when averaged.

  • shared argument with fcwt(): same changes as in fcwt().

• new unit helper functions: u() and du(): include improved physical unit treatment with the units package. Frequency and time parameters can now be "units" objects, created with u(). Allow user to adjust plot() scales to use arbitrary time/frequency units.

• new helper functions to determine the correct value of sigma for a given use case: sigma_res(), sigma_freq_res_rel(), sigma_from_time_res(), sigma_from_freq_res(), sigma_from_freq_res_rel().

• add more convenience S3 methods: print(), [], as.matrix(), rbind(), tibble::as_tibble().

• openmp_enabled()/avx_enabled() new functions to check for system OpenMP/AVX support.

• new vignette about controlling the time-frequency resolution vignette("sigma").

• add a package logo

fCWTr 0.2.1

• Initial CRAN submission.
