Pricesensitivitymeter Package v1.2 Released

An updated version of the “pricesensitivitymeter” R package is now available on CRAN: This version 1.2 includes two main new features: The new function psm_plot() is a convenience function for creating the “standard” Price Sensitivity Meter plot. You can see a simple example in the Visualizing PSM Results vignette. The psm_analysis() function now also supports input in tibble format (which is common in the “tidyverse”), in addition to standard data.
