Add arguments to $profile()

[etiennebacher]

• Add all optimization parameters
• Add arg show_plot

TODO:

• more plot-related args: figsize, truncate_nodes
• bump news

We can't test this with snapshots because the timing changes at every run. I used ggplot2 because doing the same graph with base R is just a pain, but if one of you wants to replace it with base R I don't have a problem with that.

Example:

library(polars)

countries = c(
  "France", "Germany", "United Kingdom", "Japan", "Columbia",
  "South Korea", "Vietnam", "South Africa", "Senegal", "Iran"
)

set.seed(123)
df_test = pl$LazyFrame(
  country = sample(countries, 1e7, TRUE),
  x = sample(1:100, 1e7, TRUE),
  y = sample(1:1000, 1e7, TRUE)
)$
  with_columns(contains_na = pl$col("country")$str$contains("na"))$
  sort(pl$col("country"))$
  filter(pl$col("country")$is_in(pl$lit(c("United Kingdom", "Japan", "Vietnam")))    )$
  with_columns(is_uk = pl$col("country") == "United Kingdom")

x <- df_test$profile(show_plot = TRUE)

x <- df_test$profile(show_plot = TRUE, truncate_nodes = 5)

Thanks, this is an interesting feature.
While there are other packages out there for creating great plots besides ggplot2, it makes sense to go with ggplot2 here given that it is one of the most popular R package.

Some questions:

• Would it make sense to add an option feature that would allow the display of the plot to be the default?
• I think it might be useful if the ggplot object is the return value, is it possible to do that?

I don't really see the point here

We should return a list of 3 with the two tables + the plot when show_plot = TRUE, I'll update the function

Sorry for the lack of clarity. I mean, I was imagining something like specifying it with the options function.

Nice!

Could you also update the document?

I added details on the returned value

I don't think this is necessary, this function shouldn't be called many times so that we need a global option for this

thanks :)
