fdascript: Positions of the tip of a pen in centimeters while writing in cursive script the letters "fda" twenty times.

Description

The writing was on a horizontal surface with the position of the pen recorded 400 times per second with a background noise level of about 0.05 centimeters.

Usage

fdascript

Format

An array object fdascript with dimensions 1401, 20, and 2. The first dimension is the number of observations in each record, the second is the records, and the third dimension is for the X and Y coordinate.

Details

The times are in seconds over an interval of 2.3 seconds, but in the analysis seconds are converted to "centiseconds" by multiplication by 100 in order to ensure numerical accuracy in the calculations.

Examples

# NOT RUN {
#  load the first record
fdascriptX <- fdascript[,1,1]
fdascriptY <- fdascript[,1,2]
#  Define the observation times in 100ths of a second
centisec <- seq(0,2.3,len=1401)*100
#  plot the script
plot(fdascriptX, fdascriptY, type="l")
# }
