Hello,

I have a dataframe look like this

```
df <- data.frame(TIME = rep(1:1:24,3),
DV = runif(72, min=5, max=99))
```

i want to get the statistical summary of DV at each time point

i have used the below code, which worked fine earlier , but now it is not grouping but gives the over all result

```
df2 = df %>%
group_by(TIME)%>%
summarise(q5 = quantile(DV,0.05),
q50 = quantile(DV,0.5),
q95 = quantile(DV,0.95))
```

```
print(df2)
q5 q50 q95
1 12.27739 53.75661 91.69368
```

can someone helps me to get summary at each time point .

Thnaks in advance
