Create data frame for split-plot design
Arguments
- trt.main
an integer-valued vector specifying the treatment structure at main plot level, similar to
df.crd.- trt.sub
an integer-valued vector specifying the treatment structure at sub plot level, similar to
trt.main.- label
Optional. A list of character vectors, each corresponding to a treatment factor. The name of each vector specifies the factor's name, and its elements provide the labels for that factor's levels. If no labels are provided, default labels will be used. For a single treatment factor, the default is
list(trt = c("1", "2", ...)), and for two treatment factors, the default islist(facA = c("1", "2", ...), facB = c("1", "2", ...)). For split-plot designs, the defaults are similar but include the ".main" and ".sub" suffixes for main plot and subplot factors. For example:list(trt.main = c("1", "2", ...), trt.sub = c("1", "2", ...))andlist(facA.main = c("1", "2", ...), facB.main = c("1", "2", ...), facA.sub = c("1", "2", ...), facB.sub = c("1", "2", ...)). Label sets should be arranged so that the main plot factors come first, followed by the subplot factors.- replicates
the number of experimental units (main plots) per treatment of main plot factors.
