calc_element: Calculate the element properties, by inheriting properties from its parents

# NOT RUN { t <- theme_grey() calc_element('text', t)  # Compare the "raw" element definition to the element with calculated inheritance t$axis.text.x calc_element('axis.text.x', t, verbose = TRUE)  # This reports that axis.text.x inherits from axis.text, # which inherits from text. You can view each of them with: t$axis.text.x t$axis.text t$text # }
