Hello,
If the sub-df has more than 2 rows,
tail(df[(df$Y>0.2) & (df$X<10),], 1)
Hope this helps,

I have selected a subset of a dataframe with the vector syntax (if

```
df[(df$Y>0.2) & (df$X<10),]
Got it, thanks!

You're missing a comma, this should fix it
df[(df$Y>0.2) & (df$X<10),][2, ]

I have selected a subset of a dataframe with the vector syntax (if
this is the name):
```
> df[(df$Y>0.2) & (df$X<10),]
YX
10 0.2200642 1.591589
13 0.2941828 1.485951
```
How can I select only the second row? I only managed to get the whole
