R Dataset / Package robustbase / lactic


On this R-data statistics page, you will find information about the lactic data set which pertains to Lactic Acid Concentration Measurement Data. The lactic data set is found in the robustbase R package. You can load the lactic data set in R by issuing the following command at the console data("lactic"). This will load the data into a variable called lactic. If R says the lactic 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 lactic R data set. The size of this file is about 140 bytes.
