wondering can we use pipe get gsub together? seems I can not

```
t <- c("(66.8309216,20.3991966)","(65.3337311,16.5161694)","(63.4276473,17.7292444)","(63.1711922,14.9591800)",
"(61.3011993,16.1534214)","(61.0917012,14.6663653)")
t%>%gsub('\\(','',t) %>%gsub('\\)','',t)

```

seems not work.also if there is a df and have a column called t, same data inside 

```
df$t%>%gsub('\\(','',df$t) %>%gsub('\\)','',df$t)

```

still not work. 
Anyone gives a suggestion?

This works

```
t<-gsub('\\(','',t)
t<-gsub('\\)','',t)

```
