Hello, in RMarkdown i have an output, but it is not in the document:

Here you can see de pdf generated but without the outou result.
How can I do to appear the output?

I wrote in a chunk

data %>% filter(month %in% "Jan" & pm2.5 >=20 & year >= 2010)
```{



```{r, include = T}
data %>% filter(month %in% "Jan" & pm2.5 >=20 & year >= 2010)

But it doesn´t work

thanks:

Does data get changed somewhere in the document? Does it work when run in order from top to bottom?
