Advanced health economic analysis techniques currently performed in Microsoft Excel, such as incorporating heterogeneity, time-dependent transitions and a value of information analysis, can be easily transferred to R.

In R, missing values are stored as `NA` (meaning "not applicable"). To drop `NA` observations, use the `is.na` condtion: ```{r} summary(df$wage) df <- df %>% dplyr::filter(!is.na(wage)) summary(df$wage) ``` In this case, we want R to keep *non-missing* wage...
data: observed X-squared = 15.28, df = 5, p-value = 0.009231 In C# terms, most R functions return a data structure that can be ignored, but also contain many Console.WriteLine equivalent statements that expose output. Notice that it’s up to you to decipher the m...
