FMM package: a proposal to analyze oscillatory signals in R
I. Fernández Martínez, A. Rodríguez Collado, Y. Larriba, C. Canedo, C. Rueda
Neuronal activity, electrocardiograms or circadian gene expression are just a few examples governed by oscillatory processes. Standard methods, such as Fourier decomposition, are not always suitable for the analysis of complex oscillatory signals especially nonsinusoidal shapes. Recently our research group have proposed a novel model called Frequency modulated Möbius (FMM) flexible enough to describe from sinusoidal to very asymmetric rhythmic patterns. FMM model is defined as a signal plus error model with a nonlineal parametric signal and gaussian noise.
Here, we present the FMM package, an R user-friendly software to enhance the use of FMM models. FMM is downloadable from the Comprehensive R Archive Network and includes all required functions to fit and explore single and multicomponent oscillatory signals. Moreover, it allows incorporating additional information in terms of constraints on the model parameters, generating synthetic data or visualizing the fitting process results.
Keywords: R CRAN package, Frequency Modulated Möbius (FMM) model, oscillatory processes, multicomponent signal analysis

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
