How to round all the values of a prop.table in R in one line?

You need to separate multiplication into a separate operation:

mtcars$cyl %>% table() %>% prop.table() %>% `*`(100) %>% round(2)

We can also use {} to evaluate the (...) as a whole within the %>% ... %>% before switching to the next %>%

mtcars$cyl %>%
   table() %>%
   prop.table() %>% {. * 100} %>% 
   round(2)
.
#     4     6     8 
# 34.38 21.88 43.75
