pinch force data

\description{
151 measurements of pinch force during 20 replications with time from
start of measurement.

\describe{
\item{pinch, pinchraw}{
Matrices of dimension c(151, 20) = 20 replications of measuring
pinch force every 2 milliseconds for 300 milliseconds. The
original data included 300 observations. \code{pinchraw} consists
of the first 151 of the 300 observations. \code{pinch} selected
151 observations so the maximum of each curve occurred at 0.076
seconds.
}
\item{pinchtime}{
time in seconds from the start = seq(0, 0.3, 151) = every 2
milliseconds.
}
}
}
\details{
Measurements every 2 milliseconds.
