I have two data frames,

df1 <- data.frame(gene = c("Gen1", "Gen2", "Gen4"))

df2 <- data.frame(gene = c("Gen1", "Gen2", "Gen5"))

I would like to extract the unique elements of each list, so I end up with another two data frames

df3 <- data.frame(gene = c("Gen4"))

df4 <- data.frame(gene = c("Gen5"))

Thanks in advance, Jose.

Use the `anti_join()` function from the `dplyr` package. It's description is for this specific purpose. – statstew Jun 22 '20 at 18:29

`df3 <- anti_join(df1, df2)` and `df4 <- anti_join(df2, df1)`. – Gregor Thomas Jun 22 '20 at 18:30
