1	data(shellspots)

IJDATA 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 read.ijdata function (see Examples). The list contains following data frames / vectors:

spots.x. A data frame containing x-coordinates for sample spots with each sample spot sequence in its own column.
spots.y. A data frame containing y-coordinates for sample spots.
gbs.x. A data frame containing x-coordinates for growth lines with each growth line in its own column.
gbs.y. A data frame containing y-coordinates for growth lines
main.x. A data frame containing x-coordinates for the measurement axis
main.y. A data frame containing y-coordinates for the measurement axis
sample.name. A vector containing the sample name
scaling.factor. A numeric value defining the scale of photograph in pixels / unit.
unit. A charater vector defining the unit of measurements.
