R Dataset / Package robustbase / pilot


On this Picostat.com statistics page, you will find information about the pilot data set which pertains to Pilot-Plant Data. The pilot data set is found in the robustbase R package. You can load the pilot data set in R by issuing the following command at the console data("pilot"). This will load the data into a variable called pilot. If R says the pilot data set is not found, you can try installing the package by issuing this command install.packages("robustbase") 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 pilot R data set. The size of this file is about 140 bytes.

Pilot-Plant Data


Pilot-Plant data from Daniel and Wood (1971). The response variable corresponds to the acid content determined by titration and the explanatory variable is the organic acid content determined by extraction and weighing. This data set was analyzed also by Yale and Forsythe (1976).




A data frame with 20 observations on the following 2 variables.


Organic acid content - extraction


Acid content - titration
