问题描述
我输入 df
我想删除重复的行, :
RAW.PVAL GR allrl Bak
0.05 fr EN1 B12
0.05 fg EN1 B11
0.45 fr EN2 B10
0.35 fg EN2 B066
我的输出:
RAW.PVAL GR allrl Bak
0.05 fr EN1 B12
0.45 fg EN2 B10
0.35 fg EN2 B066
我尝试过 df< - subset(df,!duplicated(allrl,RAW .PVAL))
,但是我不会删除这两列同时重复的行。
谢谢!
解决方案
如果您想使用子集
,您可以尝试:
#RAW.PVAL GR allrl Bak
#1 0.05 fr EN1 B12
#3 0.45 fr EN2 B10
#4 0.35 fg EN2 B066
但是,我认为@ thelatemail的方法会更好
df [!duplicateated(df [c(RAW.PVAL,allrl)])]
I would like to delete duplicate rows based in two collumns, instead just one.
My input df
:
RAW.PVAL GR allrl Bak
0.05 fr EN1 B12
0.05 fg EN1 B11
0.45 fr EN2 B10
0.35 fg EN2 B066
My output:
RAW.PVAL GR allrl Bak
0.05 fr EN1 B12
0.45 fg EN2 B10
0.35 fg EN2 B066
I had tried df<- subset(df, !duplicated(allrl, RAW.PVAL))
, but I do not work to delete rows with this two columns simultaneously duplicated.
Thank you!
解决方案
If you want to use subset
, you could try:
subset(df, !duplicated(subset(df, select=c(allrl, RAW.PVAL))))
# RAW.PVAL GR allrl Bak
#1 0.05 fr EN1 B12
#3 0.45 fr EN2 B10
#4 0.35 fg EN2 B066
But, I think @thelatemail's approach would be better
df[!duplicated(df[c("RAW.PVAL","allrl")]),]
