我正在試圖查看源代碼。例如cook.distance()。這是我曾嘗試如何查看R的源代碼
cooks.distance
function (model, ...)
UseMethod("cooks.distance")
<bytecode: 0x3f25b5c>
<environment: namespace:stats>
然後我想:
debug(cooks.distance)
,並沒有什麼。然後我想:
methods(cooks.distance)
[1] cooks.distance.glm* cooks.distance.lm*
Non-visible functions are asterisked
然後我想:
lm:::cooks.distance.default
Error in loadNamespace(name) : there is no package called ‘lm’
有人告訴我LM是在大衆包,所以我嘗試了以下內容:
MASS:::cooks.distance.default
Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :
object 'cooks.distance.default' not found
我如何可以查看源碼?我試圖查看源代碼但找不到函數?
看起來像它在'stats'包,不'MASS'。試試'stats ::: cooks.distance.lm'。 – joran 2013-03-22 20:14:37

謝謝他們都做到了 – user1871528 2013-03-22 20:32:49
