This vignette documents the most common use cases and patterns for the profrep package.
To use profrep, you will have to start with lab work! As described on the home page, one of the most common measurements that stress physiologists take is blood samples for corticosterone quantification during a stress response.
First, we will install the package from CRAN:
Next, we will load in a data set from a csv. This would take the form
of data <- read.csv(<path_to_csv>). Instead of
loading in new data, this vignette will make use of one of the three
example data sets provided with profrep. We shall use the
synthetic data created for this purpose, which consists of 11
individuals, which had four replicates sampled at 4 different times.
To load in, we call the data from the profrep
package:
synthetic_data <- profrep::synthetic_data_four_point
print(synthetic_data)

Since we know how many trials we performed, we can easily perform the profile repeatability calculation with
If we wanted logs to be displayed in the terminal, we would have
changed the default verbosity factor from FALSE to
TRUE with verbose = True.
The results of the calculation are below:

individual, with a profile-repeatability score of 0.9925!
