Thanks, Bert. ?which.max confirmed that's all I need to find the maximum
value.

Now I need to read more than ?filter to learn why I'm not getting the
relevant row with:
> which.max(pdx_disc$cfs)
[1] 8054

> filter(pdx_disc, cfs == 8054)
# A tibble: 0 × 9
# … with 9 variables: site_nbr <chr>, year <int>, mon <int>, day <int>,
#   hr <dbl>, min <dbl>, tz <chr>, cfs <dbl>, sampdt <dttm>

Regards,

Rich
