Re: [R] save(), load(), saveRDS(), and readRDS()

Ivan Krylov points out that load(file, e <- new.env()) is cumbersome. I put it into a function. Regards, Jorgen Harmse. #' Save & load lists & environments #' #' \code{\link{save}} has to be told what to save from an environment, and the obvious way #' to save a structure creates an extra l

Re: [R] lattice densityplot with weights

Yes, the following should (mostly) work: lattice::densityplot(~ x, mydf, groups = name, weights = wt, auto.key = list(space = "inside"), grid = TRUE) I just realised that the 'subdensity' and 'warnWbw' arguments are not passed through by densityplot(), so there is no way to get rid of the cor

Re: [R] lattice densityplot with weights

Unless I misunderstand... 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. Cheers, Bert On Fri, Sep 29, 2023 at 3:32 AM Naresh Gurbuxani < naresh_g

Re: [R] replace character by numeric value

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 woul

Re: [R] replace character by numeric value

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

Re: [R] replace character by numeric value

Does this work? mynewdf$side <- as.numeric(mynewdf$side) This code would be the next line after your mutate. TIm -Original Message- From: R-help On Behalf Of Enrico Schumann Sent: Thursday, September 28, 2023 3:13 AM To: arnaud gaboury Cc: r-help Subject: Re: [R] replace character by

Re: [R] Odd result

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? -pd > On 24 Sep 2023, at 11:58 , Michael Dewey wrote: > > Dear David > > To get the first 46

[R] lattice densityplot with weights

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 mydf <
