R package for visualizing/analyzing accelerometry data?
Hello All - Any recommendations or suggestions for neat ways to visualize data taken from a 3-axis accelerometer? My study species is aquatic, so I would be interested in movement in the 3 dimensions in addition to being able to incorporate the time series as well. Is there a package in R that might be useful for this? Thank you in advance, Jen ~~~~~~~~~~~~~~~~~~~~~ Jennifer Maresh, PhD Student Center for...

"Zoomable" time series plots
Not sure if the question is appropos, but I have multiple csv's which are read into an xts object, corresponding to telemetry data (accelerometer, magnetometer/compass, and gyroscope). For examination, it would be ?ber useful if plot.zoo (or something similar) allowed me to zoom in and out of a subset of the time axes. -- Sent from my mobile device Envoyait de mon portable

Vibration signal prediction in R
I have a vibration signal coming accelerometer. I converted this signal from* m/s^2* to *mm/s*. Now I am supposed to predict this vibration signal in R using historical data. (Please see the attached picture of vibration signal). Can I use this vibration signal just like that to the prediction using predictive Models or Do i need to do some pr...

NFFT on a Zoo?
I have an irregular time series in a Zoo object, and I've been unable to find any way to do an FFT on it. More precisely, I'd like to do an NFFT (non-equispaced / non-uniform time FFT) on the data. The data is timestamped samples from a cheap self-logging accelerometer. The data is weakly regular, with the following characteristics: - short gaps every ~20ms - large gaps every ~200ms - jitter/noise in the timestamp The gaps cover ~10% of the acquisition time. And they occur often enough that the uninterrupted portions of the data are too short to yield usefu...

Time series data with dropouts/gaps
I have time-series data from a pair of inexpensive self-logging 3-axis accelerometers (http://www.gcdataconcepts.com/xlr8r-1.html). Since I'm not sure of the vibration/shock spectrum I'm measuring, for my initial sensor characterization run the units were mounted together with the sample rate set to the maximum of 640 samples/sec. Unfortunately, at this sample rate there...

display, accelerometer/motion sensor being the first 4 for release (though 81 have been mocked up so far). The long term concept is if you want a 'weather station with live video feeds and gps location control you can add various modules together to deliver what you are looking to achieve. I have high hopes for the...

Data manager in a Spatial Ecology lab, Univ Florida, Fort Lauderdale FL
...Data Manager will be to manage the group's database system: we run a PostgreSQL/PostGIS database system on a Linux server, which hosts telemetry data on wood storks, sea turtles, raccoons, and associated GIS layers. In the near future, we will be adding advanced data from albatrosses, including accelerometers and infrasound. The Data Manager will manage the database server (database design, manual and automated data entry, metadata, set permissions for users and groups, backups, development of web apps to access and display data, etc.). Additional responsibilities will include assisting members of the...

Finding Instances of a Pattern Throughout Data Set
I have approximately 2.5 million rows from a number of sensor readings. Having plotted these, I can see a given pattern (say a spike in the amplitude away from the mean). I would now like to automate this procedure as we're expecting a great deal more data in the near future. Is there any package or function that will make this possible? Many thanks! I suppose, I could do something like:
