Measure Growth Patterns and Align Sampling Spots in Photographs

shellspots function

<code>IJDATA</code> object. A list containing ImageJ ROI information about sample spots and growth lines along a bivalve mollusk shell section. The information is acquired by running "shellspots.zip" dataset through the <code><a rd-options="" href="/link/read.ijdata?package=sclero&version=0.2" data-mini-rdoc="sclero::read.ijdata">read.ijdata</a></code> function (see Examples). The list contains following data frames / vectors:
<ul>
<li> spots.x. A data frame containing x-coordinates for sample spots with each sample spot sequence in its own column.
  </li>
<li> spots.y. A data frame containing y-coordinates for sample spots.
  </li>
<li> gbs.x. A data frame containing x-coordinates for growth lines with each growth line in its own column.
  </li>
<li> gbs.y. A data frame containing y-coordinates for growth lines
  </li>
<li> main.x. A data frame containing x-coordinates for the measurement axis 
  </li>
<li> main.y. A data frame containing y-coordinates for the measurement axis 
  </li>
<li> sample.name. A vector containing the sample name
  </li>
<li> scaling.factor. A numeric value defining the scale of photograph in pixels / <code>unit</code>.
  </li>
<li> unit. A charater vector defining the unit of measurements.
</li>
</ul>
