从字符向量中删除重复的字符串

如何从这个字符向量中有效地删除重复项？从字符向量中删除重复的字符串

> dput(data[1:30]) 
c("AT2G27020 AT3G26340", "AT1G56450 AT3G26340", "AT1G13060 AT3G26340",

我曾尝试使用简单的功能为：unique和duplicated但遗憾的是它没有工作。

这是我的不好。通过重复我是指相同的AGIs，因此它们中的一些一起存储在“”中并不重要。我希望每个“ATXG ...”只有一次在我的向量中。在开始时我并不知道矢量包含它们对...对不起。

你究竟做了什么（代码），什么没有工作？ _entire_字符串上的'unique'和'duplicated'工作。你想删除什么“重复”？ – hrbrmstr

您的示例不包含重复项... – Cath

您的字符串格式为“”text1 text2“”。你是否想看看这两个值是否相等？ 'text1 == text2'？ –

unique(unlist(strsplit(x, " "))) 
#[1] "AT2G27020" "AT3G26340" "AT1G56450" "AT1G13060" "AT3G22630" "AT3G22110" 
#[7] "AT2G05840" "AT1G47250" "AT1G79210" "AT5G40580" "AT3G27430" "AT4G31300" 
#[13] "AT3G14290" "AT5G35590" "AT3G60820" "AT1G53850" "AT5G66140" "AT3G51260" 
#[19] "AT1G21720" "AT4G14800"
