leafArea function

data

Arabidopsis leaf area data for the hapmap and Swedish regmap population.

data(LA_H); data(LA_S)

Format

Data frame with leaf area observations:

• genotype: a factor, the levels being the accession identifiers
• LA13_H: Leaf area 13 days after sowing, in numbers of pixels (hapmap)
• LA13_S: Leaf area 13 days after sowing, in numbers of pixels (Swedish regmap)
• replicate: The replicate (or block) each plant is contained in (factor with levels 1 to 4)
• rep1: numeric encoding of the factor replicate: equals 1 if the plant is in replicate 1 and 0 otherwise
• rep2: numeric encoding of the factor replicate: equals 1 if the plant is in replicate 2 and 0 otherwise
• rep3: numeric encoding of the factor replicate: equals 1 if the plant is in replicate 3 and 0 otherwise
• x: The within image x-coordinate of the plant. A factor with levels 1 2 3
• y: The within image y-coordinate of the plant. A factor with levels 1 2 3 4
• x1: numeric encoding of the factor x: equals 1 if the plant is in position 1 and 0 otherwise
• x2: numeric encoding of the factor x: equals 1 if the plant is in position 2 and 0 otherwise
• y1: numeric encoding of the factor y: equals 1 if the plant is in position 1 and 0 otherwise
• y2: numeric encoding of the factor y: equals 1 if the plant is in position 2 and 0 otherwise
• y3: numeric encoding of the factor y: equals 1 if the plant is in position 3 and 0 otherwise
