The query "when does r" appears incomplete, but it seems to be asking about "when does R" in some context, likely related to the R programming language or a specific function in R. Based on search results, here are possible relevant clarifications:
- R is a programming language for statistical computing and data visualization, started in the early 1990s and first released publicly in 1993, with version 1.0 released in 2000. It is interpreted, so R code executes immediately without compilation.
- The search also found a function called "when" in R's purrr package, which is used for condition-action matching—executing the first matching action and returning its result.
- There is no direct question like "when does R do something" completely answered, so more context would help.
If the question is "When does R execute code?"—R is an interpreted language, so execution occurs as the interpreter reads the code line by line.
If the question is about "when" function in R (from the purrr package), it evaluates a value against conditions and executes the first matching action.
If more precision is needed, please provide additional context or clarify.
