R Dataset / Package boot / salinity

On this R-data statistics page, you will find information about the salinity data set which pertains to Water Salinity and River Discharge. The salinity data set is found in the boot R package. You can load the salinity data set in R by issuing the following command at the console data("salinity"). This will load the data into a variable called salinity. If R says the salinity data set is not found, you can try installing the package by issuing this command install.packages("boot") and then attempt to reload the data with the library() command. 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 salinity R data set. The size of this file is about 506 bytes.

Format

This data frame contains the following columns:

sal

The average salinity of the water over two weeks.

lag

The average salinity of the water lagged two weeks. Since only spring is used, the value of lag is not always equal to the previous value of sal.

trend

A factor indicating in which of the 6 biweekly periods between March and May, the observations were taken. The levels of the factor are from 0 to 5 with 0 being the first two weeks in March.

dis

The amount of river discharge during the two weeks for which sal is the average salinity.
