This package contains a list of functional time series, sliced functional time series, and functional data sets. Functional time series is a special type of functional data observed over time. Sliced functional time series is a special type of functional time series with a time variable observed over time.

The experiment involved varying the composition of biscuit dough pieces. Two sets of dough pieces were measured, a calibration set and a prediction set. They were created and measured as two distinct sets, on separate occasions, and do not result from a random (or any other) split of a larger set.
data(labp) data(labc) data(nirp) data(nirc)data(labp) data(labc) data(nirp) data(nirc)
nirp and nirc are objects of class fds.
labp and labc are objects of class matrix.
The data labc (c stands for calibration) and labp (p stands for prediction) contain the reference data on the composition of the doughs.
The data nirc and nirp contain 700 point near infrared reflectance (NIR) spectra for the same dough. The spectral range is 1100-2498 nm in steps of 2nm.
The data labc$y is 4 rows by 40 columns, the rows being fat, sucrose, flour and water all in percents. The percents do not quite add
up to 100, since there are other minor ingredients present, but they add up to nearly 100 percent.
According to Brown et al. (2001), the observation 23 in the calibration set appears as an outlier.
Sample number 21 in the labp shows up as a validation set.

The data were registered by the satellite topex/poseidon around an area of 25 kilometers upon the Amazon River. Each row of the data matrix is represented by its wave (i.e. curve) on the range (0, 70), and the satellite is registering 10 curves each second.

Note that each wave is linked with the kind of ground treated by the satellite, and the idea for the Amazonian basin is to use these waveforms for altimetric and hydrological purposes.
