Still not the correct syntax. Command is now:
disc_by_month %>%
group_by(year, month) %>%
summarize(disc_by_month, vol = mean(cfs, na.rm = TRUE))
and results are:
source('disc.R')
`summarise()` has grouped output by 'year', 'month'. You can override using the
`.groups` argument.
disc_by_month
# A tibble: 590,940 × 6
# Groups: year, month [66]
year month day hour min cfs

The grouping is still not right. I expected to see a mean value for each
month of each year in the data set, not for each minute.
