使用rpy2 importr將R包Rssa導入到python中

Question

當我在Python命令中執行時

rssa = importr('Rssa')

我得到了eroor

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    rssa = importr('Rssa')

    version = version)

    raise ValueError("Error: '%s' already in the translation table. This means that the signature of the R function contains the parameters '%s' and/or '%s' <sigh> in multiple copies." %(r_param, r_param, prm_translate[py_param]))
ValueError: Error: '...' already in the translation table. This means that the signature of the R function contains the parameters '...' and/or '...' <sigh> in multiple copies.

例如，其他包導入沒有問題

stats = importr('stats')
tseries = importr('tseries')
forecast = importr('forecast')

我一直在尋找這樣的問題，但我找不到任何接近的東西。 請提出一些關於這個問題的決定。

Answer 1

這是由於Rssa在試圖控制'分解'功能（從'stats'包中導出）時的錯誤引起的。 特別是，在正式列表'...'中添加兩次，這就是rpy2抱怨的內容。

這將在隨后的Rssa版本中修復。

唯一的解決方法是在R / common.R中注釋掉以下行：

formals(decompose.default) <- c(formals(decompose.default), alist(... = ))

並從源代碼重新安裝Rssa。 這在Windows上可能並不重要，盡管R windows構建器可以在這里提供幫助。
