Ivan Krylov points out that load(file, e <- new.env()) is cumbersome. I put it
into a function.

Yes, the following should (mostly) work:

See ?panel.densityplot
Lattice functions do their work through a host of panel functions,
typically passing their ... arguments to the panel functions.
panel.densityplot has a weights argument.

You might also try
mynewdf <- mydf |> dplyr::mutate(side = ifelse(side == 'BUY', 1,-1))
This may give unexpected results if there are other choices besides "BUY" and
"SELL".
mynewdf <- mydf |> dplyr::mutate(side = ifelse(side == 'BUY', 1, ifelse(side ==
'SELL', -1, NA)))
is an option that
The reason you're getting the result as character is that you have
'side' as your alternative result in the second ifelse(). If "BUY" and
"SELL" are the only options you might try
ifelse(side == 'BUY', 1, ifelse(side == 'SELL', -1, NA))
or
c(1,-1)[match(side, c("BUY", "SELL"))]
or
Does this work?
mynewdf$side <- as.numeric(mynewdf$side)
This code would be the next line after your mutate.

Yes. Also notice that something fishy seems to be going on in columns 2 and 3
(assuming that the date/time is 1 column).
They appear to be read as character data, even though the content is numeric?

density() function in R accepts weights as an input. Using this
function, one can calculate density and plot it. Is it possible to
combined these two operations in lattice densityplot()?
mydf <- data.frame(name = "A", x = seq(-2.9, 2.9, by = 0.2), wt =
diff(pnorm(seq(-3, 3, by = 0.2

There's the load(file, e <- new.env()) idiom, but that's potentially
a lot to type.
ESS needs C:/Programme/R/R-4.2.2/bin/R.exe
I'm not sure if I'm missing something but it seems to me that you want to
define it in your init file, but then you will have to update it each time
that you change R versions. Use the following line
