如何在R中选择带有星号的变量

由小鸡鸡发布于 2020-04-09 05:44:25

I want to select some variables from my csv file in R. I used this select(gender*, age*), but got the error - object not found. I tried select(`gender*`, `age*`) and select(starts_with(gender), starts_with(age)), but neither works. Does anyone know how to select variables with star symbols? Thanks a lot!

It is possible that the select from dplyr is masked by select from any other package as this is working fine. Either specify the packagename with :: or do this on a fresh R session with only dplyr loaded

library(dplyr)
data(iris)
iris$'gender*' <- 'M'
iris%>% 
      head %>% 
      dplyr::select(`gender*`)
#   gender*
#1       M
#2       M
#3       M
#4       M
#5       M
#6       M
