I think I was able to reproduce it.
```r
library(tidyverse)
library(arrow)
file <-
curl::curl_download("https://download849.mediafire.com/r4csstfcwwwgGquvCho4H6GtScoCJac108RL-q6X9MtoWuPDQvZOQAWhxQqlCjLj2RmsyzikhTZ0ijBElIAs5in5whbp-w/7dk60h8gnj4n1qj/bioargo_correction_b.parquet";,
destfile = tempfile(fileext = ".parquet"))
bioargo <- read_parquet(
file
)
bioargo
bioargo |>
group_by(takuse, date_time, n_prof) |>
filter(pres == max(pres)) |>
ggplot(aes(x = pres)) +
geom_histogram(binwidth = 10, color = "white")
bioargo_dark_corrected <- bioargo |>
group_by(takuse, date_time, n_prof) |>
mutate(chla = chla - min(chla, na.rm = TRUE)) |>
ungroup()
write_parquet(
bioargo_dark_corrected,
tempdir()
)
```
Can you confirm?
