I have a set of data which I would like a subset of. I would like the subset defined as those rows with a value for variable X which appears more than once. Variable X is a string.
我有一组数据,我想要一个子集。我希望子集定义为具有变量X值的那些行,它们出现不止一次。变量X是一个字符串。
So, for example, if x consisted of ('help','me,'me','with','this','this'), it would return the rows with the x values ('me','me','this,'this').
所以,例如,如果x由('help','me','me','with','this','this')组成,它将返回带有x值的行('me','me' ”, '这个,' 这个)。
Thank you so much for your help!
非常感谢你的帮助!

Something like this should work:
像这样的东西应该工作:
x <- c('help','me','me','with','this','this')
x[duplicated(x, fromLast=TRUE) | duplicated(x)]
