## pinch force data

### Description

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

### Usage

    pinch
    pinchraw
    pinchtime

### Format

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. `pinchraw` consists of the first 151 of the 300 observations. `pinch` selected 151 observations so the maximum of each curve occurred at 0.076 seconds.

pinchtime

  time in seconds from the start = seq(0, 0.3, 151) = every 2 milliseconds.

### Details

Measurements every 2 milliseconds.
