My tuneR sawtooth wave function generator is broken. When I use the sine function, I get exactly what I expect: a sine wave whose frequency is defined by the freq parameter. In particular, higher frequencies have shorter wavelengths (more cycles...

I sent this message to the maintainer's email address listed on the signal package, but it bounced. Perhaps somebody on this list has more insight into the signal package than I do (or knows the maintainer's new address...

Here is perhaps a better sawtooth wave generator: sawtooth <- function(freq, duration = samp.rate, from = 0, samp.rate = 44100, bit = 1, stereo = FALSE, xunit = c("samples", "time"), reverse = FALSE, ...){ xunit <- match.arg(xunit) durFrom <- preWaveform(freq = freq, duration = duration, from...

Greetings Matthias, Thanks again for your sound module. I did not ever manage to find the time to play with phase equations, but I found I needed the module for a new project involving bats. I needed to do some...

Dear list, I am trying to re-analyse something. I do have two time series, one of which (ts.mar) might help explaining the other (ts.anr). In the original analysis, no-one seems to have cared about the data...
