Question

我正在尝试使用rpy2中R Forecast软件包中的stlm函数。但是，我不断收到以下错误。

traindf = https://vincentarelbundock.github.io/Rdatasets/csv/datasets/UKgas.csv

代码：将熊猫作为pd导入从rpy2.robjects.packages导入导入器

ts=robjects.r('ts')
forecast=importr('forecast', lib_loc= '/dp/softwares/rstudio/r_lib/')

from rpy2.robjects import pandas2ri
pandas2ri.activate()


traindf = 'link to dataset is above'

rdata=ts(traindf.value.values,frequency=4)
forecast.stlm(rdata, s_window = "periodic" , robust = True , method = "ets")

输出：

/dp/softwares/anaconda3/lib/python3.6/site-packages/rpy2/rinterface/__init__.py:146: RRuntimeWarning:

Error in if (ncol(x) == 1L) { : missing value where TRUE/FALSE needed

我已经在Google上寻找类似的问题，并且提到评估缺失值（NA）是一个问题（需要一个数字）。

但是，我不确定如何解决此问题。感谢您的帮助。
