I think you are being dishonest. That code does not appear on hrbrmstr'svignette at least in a form that I recognize.

When I run your code from the first posting with all the instances of`com_num` replaced by `com_name` and removing the `pointer` entry in datwhich throws an error when trying to define dat, I get

Error in `group_by()`: ! Must group by variables found in `.data`. ✖Column `com_name` is not found. So I "rewind the process to the pointwhere the error is reported and find

dat %>%+ select(year, month, company, share, com_name) %>% +

tidyr::gather(company, share, -year) # A tibble: 148 × 3 year companyshare <dbl> <chr> <chr> 1 2018 month 12 2 2019 month 1 3 2019 month 2 42019 month 3 5 2019 month 4 6 2019 month 5 7 2019 month 6 8 2019 month 79 2017 month 1 10 2017 month 2 # … with 138 more rows # ℹ Use `print(n =...)` to see more rows So the "gathering" process seems to have removedthe `com_name` column. Can exit R without saving your workspace and thenconstruct a series of R commands that will create a reproducibleexample? -- David.

Actually in my main data the column name is com_num ( wheremistakenly I pasted the sample data here under the com_name ). So,when I run the command successfully this is the error shows up -

  2. ├─streamgraph::sg_legend(., show = TRUE, label = "Share: ")

  9. ├─dplyr::group_by(., year, com_num)
 10. └─dplyr:::group_by.data.frame(., year, com_num)

11. └─dplyr::group_by_prepare(.data, ..., .add = .add, caller_env =caller_env())

 12.     └─rlang::abort(bullets, call = error_call)

Any suggestions on how I can fix it ??

    I don’t see a column with the name ‘com_num’, so the error message
    makes complete sense.
