iris2_tab
A tabular
object as produced by version 0.9.6 of the tables
package by Duncan Murdoch (https://CRAN.R-project.org/package=tables
).
The table was produced with the following code, starting from the
iris2
data frame:
iris2_tab <- tables::tabular( Species*Heading()*value*Format(digits=2)*(mean + sd) ~ Heading("Flower part")*flower_part*Heading()*direction, data=iris2)
Fisher, R. A. (1936) The use of multiple measurements in taxonomic problems. Annals of Eugenics, 7, Part II, 179–188.
The data were collected by Anderson, Edgar (1935). The irises of the Gaspe Peninsula, Bulletin of the American Iris Society, 59, 2–5.
