It's the cut and paste monster. Somewhere along the way, the final " got 
converted to ” which R does not see.

Subject: [R] WG: Fw: Re: dplyr : row total for all groups in dplyr summarise

Hi All,

if I run the suggested code

mtcars %>%
  group_by (am, gear) %>%
  summarise (n = n()) %>%
  mutate(rel.freq = paste0(round(100 * n / sum(n), 0), "%")) %>%
  ungroup() %>%
  plyr::rbind.fill(data.frame(n = nrow(mtcars), rel.freq =
                                              "100%”))

I get

> mtcars %>%
+   group_by (am, gear) %>%
+   summarise (n = n()) %>%
+   mutate(rel.freq = paste0(round(100 * n / sum(n), 0), "%")) %>%
+   ungroup() %>%
+   plyr::rbind.fill(data.frame(n = nrow(mtcars), rel.freq =
+                                               "100%”))




+ 


R stops execution cause something within the prgram syntax is missing.

What has to be changed to be able to run the code?

Kind regards

Georg Maubach
