R Dataset / Package DAAG / codling

Documentation

On this Picostat.com statistics page, you will find information about the codling data set which pertains to Dose-mortality data, for fumigation of codling moth with methyl bromide. The codling data set is found in the DAAG R package. You can load the codling data set in R by issuing the following command at the console data("codling"). This will load the data into a variable called codling. If R says the codling data set is not found, you can try installing the package by issuing this command install.packages("DAAG") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the codling R data set. The size of this file is about 6,509 bytes.
