推荐答案

这可能是数据集（ str（PkgMYaseen208））属性的问题。一种选择是转换为 data.frame ，然后 select

It could be an issue with the attributes of the dataset (str(PkgMYaseen208)). One option is to convert to data.frame and then select

library(dplyr)
PkgMYaseen208 %>% 
  as.data.frame %>% 
  dplyr::select(package)
#          package
#1      agriTutorial
#2         bayesammi
#3      baystability
#4  DiallelAnalysisR
#5              dmai
#6         eda4treeR
#7              gvcR
