Digitized growth increments in cross section of modern oyster.
Description
A dataset containing X- and Y-coordinates of digitized growth increments from the Crassostrea gigas #1 oyster used as an example in de Winter (2017)
Usage
data(O1_input)
Format
A data frame with 181 rows and 26 variables:
- x_base
X-coordinate in pixels of bottom line on image
- y_base
Y-coordinate in pixels of bottom line on image, second row value represents the day of the year
- EMPTY1
Empty column
- x_top
X-coordinate in pixels of top of Crassostrea gigas shell #1 (increment 0)
- y_top
Y-coordinate in pixels of top of Crassostrea gigas shell #1 (increment 0), second row value represents the age in days (=0)
- EMPTY2
Empty column
- x_1
X-coordinate in pixels of increment 1
- y_1
Y-coordinate in pixels of increment 1, second row value represents the age in days
- EMPTY3
Empty column
- x_2
X-coordinate in pixels of increment 2
- y_2
Y-coordinate in pixels of increment 2, second row value represents the age in days
- EMPTY4
Empty column
- x_3
X-coordinate in pixels of increment 3
- y_3
Y-coordinate in pixels of increment 3, second row value represents the age in days
- EMPTY5
Empty column
- x_4
X-coordinate in pixels of increment 4
- y_4
Y-coordinate in pixels of increment 4, second row value represents the age in days
- EMPTY6
Empty column
- x_5

- EMPTY7
Empty column
- x_6
X-coordinate in pixels of increment 6
- y_6
Y-coordinate in pixels of increment 6, second row value represents the age in days
- EMPTY8
Empty column
