Data on life history traits for the
invasive California wild radish Raphanus sativus
Usage
radish
Format
A data frame with records for 286 plants.
Data are already in “long” format; no need to reshape.
resp
Response vector.
varb
Categorical. Gives node of graphical model corresponding
to each component of resp. See details below.
root
All ones. Root variables for graphical model.
id
Categorical. Indicates individual plants.
Site
Categorical. Experimental site where plant was grown.
Two sites in this dataset.
Block
Categorical. Block nested within site.
Region
Categorical. Region from which individuals
were obtained: northern, coastal California (N) or southern, inland
California (S).
Pop
Categorical. Wild population nested within region.
varbFlowering
Indicator (zero or one). Shorthand
for as.numeric(radish$varb == "Flowering").
varbFlowers
Indicator (zero or one). Shorthand
for as.numeric(radish$varb == "Flowers").
fit
Indicator (zero or one). Shorthand
for as.numeric(radish$varb == "Fruits"). So-called because the
components of outcome indicated are the best surrogate of
Darwinian fitness in these data.
Details
The levels of varb indicate nodes of the graphical model to which
the corresponding elements of the response vector resp belong.
This is the typical “long” format produced by the R reshape
function. For each individual, there are several response variables.
All response variables are combined in one vector resp.
The variable varb indicates which “original” variable
the number was for. The variable id indicates which individual
the number was for. The levels of varb, which are the names
of the “original” variables are
Flowering
Indicator (zero or one). Bernoulli, One if individual
survived to produce flowers.
Flowers
Integer. Zero-truncated Poisson, number of flowers observed.
Fruits
Integer. Poisson, number of fruits observed.
Graphical model is
1 -> Flowering -> Flowers -> Fruits.
