Scrpit R与熊猫

Question

我实际使用R来删除重复的序列，例如：

seq1      seq2 
seq2      seq1 
seq3      seq4 
seq5      seq6

并获取

seq1      seq2
seq3      seq4 
seq5      seq6

做：

data<-read.table("dataframe.txt")

for (i in 1:nrow(data))
{
  data[i,c(2,3)] = sort(data[i,c(2,3)])
}

data2 = data[!duplicated(data[,c(2,3)]),]

write.csv(data2,"data_without_duplicated")

有人知道如何用熊猫做这件事吗？

以下是真实数据的示例：

这是我的剧本：

data_wo_eqSpec.to_csv("dataframe.txt", sep='\t')
print("prem1:",data_wo_eqSpec.shape)

data_wo_eqSpec=data_wo_eqSpec.astype(str) 
data_wo_eqSpec.iloc[:,1:3]=np.sort(data_wo_eqSpec.iloc[:,1:3].values,1)

data_wo_eqSpec2= data_wo_eqSpec.drop_duplicates(list(data_wo_eqSpec.iloc[:,1:3]))

print("prem:",data_wo_eqSpec2.shape)

data_wo_eqSpec=pd.read_csv("data_without_duplicated")

print("deus:",data_wo_eqSpec.shape)

以下是数据：data
