[R] Spectra for continious time

[Martin Albers]

Is there any way to apply a spectra or periodogramm to my time series.

My first problem is, that I do not know how to get a spectra/periodogramm for my data.

I have found time series tools but nothing for spectral analysis.

My second problem: The time series function I have found, wanted a discrete timeline, but my timeline is continious.

Kind regards
