dt[, as.list(func(.SD[[1]], ...)), by = sim_number, .SDcols = .x],
id.var = "sim_number",
value.name = func_chr
```
Now passing `..…
-
Add param of .value_col to function because if the column value does not exists the function fails.
-
Make a function that does lagged correlation and outputs the lagged tibble, correlation matrix, correlation long tibble, lagged plot and correlation matrix heatmap

When used without tidyeval, `across()`, `arrange()`, `group_by()` can execute without a problem even if no arguments are passed to them. One would expect the same behavior with tidyeval, but this is n…

### loads required libraries
```{r}
library(tidyverse)
library(tidytext)
```
### creates to 2-row tibble, test simple operation (it works)
```{r}
df % select(id,descr) %>% unnest_tokens(word,de…

Can use traditional 0 1 scale which `hai_scale_zero_one_vec()` does or use `z-score standardization`
`X_new = (X - mean(x)) / sd(x)`
