fer function of indicoio saying Error: could not find function "fer"

fer function of indicoio saying Error: could not find function "fer"

我从

安装了 indicoio 包
devtools::install_github("IndicoDataSolutions/IndicoIo-R")

但是也安装了以前的版本。我也尝试使用

卸载它
remove.packages("indicoio")

并重新安装。

然后当我尝试使用

fer(imageLocation,api_key)

imageLocation = path.expand("~/R/funwithR/data/photoforanalysis.png")

我收到错误提示

Error: could not find function "fer"

还有

library(indicoio)

给予

Warning messages:
1: In if (content == "") { :
the condition has length > 1 and only the first element will be used
2: In if (content == "") { :
the condition has length > 1 and only the first element will be used

但是

image_features(imageLocation,apikey)

有效

好像不是

fer(imageLocation,api_key)

提供 errors.Another 函数

face_emotion(imageLocation,api_key)

正在工作。

"FER is simply our alias function for face_emotion. So neither will be deprecated any time soon.",正如来自 indico 的 Chris 所说。

所以,另一个似乎没问题。
