To install the package run the following command in R.
install.packages("CPMIstats_0.1.3.tar.gz", repos = NULL)
Alternatively, the package can be installed by using the install_github function from the R package devtools. The steps for this installation are given in the CPMI_calls.R file. This method may make it easier to keep the most up to date version.
CPMI_calls.R is an example file with a list of all the functions in the package. For more information on the functions
type ?function_name.
Update: version 0.1.3 requires the time column of the payments data to be converted to a hms class, the command to do this is given in CPMI_calls.R.
