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

### Description

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

### Usage

1 |

### 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
