Question

我的ROCR很好。我需要confusionMatrix的摘要。

caret::confusionMatrix(pred,test$abc)  # NOT WORKING

运行上面的代码时，出现以下错误

loadNamespace（i，c（lib.loc，.libPaths（）），versionCheck = vI [[i]]）中的错误：没有名为“食谱”的软件包

我尝试在此处搜索答案并执行

install.packages(caret,dependencies = TRUE)
install.packages('caret', dependencies=c('ddalpha', 'recipes'))

工具->安装软件包
开始新的会话
重新启动RStudio

在我开始探索性数据分析之前执行install.packages(caret)和library(caret)时，我得到以下消息：

install.packages('caret')
also installing the dependency ‘recipes’

  There is a binary version available but the source version is later:
        binary source needs_compilation
