Dear Ron and Bert, First (and without considering why one would want to do this, e.g., adding a start of 1 to the data), the following works for me: ------ snip ------ > library(MASS) > BoxCoxLambda <- function(z){ + b <- boxcox(z + 1 ~ 1, + lambda = seq(-5, 5, length.out = 101), + plotit = FALSE) + b$x[which.max(b$y)] + } > mrow <- 500

No, I'm afraid I'm wrong. Something went wrong with my R session and gave me incorrect answers. After restarting, I continued to get the same error as you did with my supposed "fix." So just ignore what I said and sorry for the noise. -- Bert On Sat, Jul 8, 2023 at 8:28?AM Bert Gunter <bgunter.4567 at gmail.com> wrote: > Try this for your function: > >

Thanks John. ?boxcox says: ************************* Arguments object a formula or fitted model object. Currently only lm and aov objects are handled. ************************* I read that as saying that boxcox(lm(z+1 ~ 1),...) should run without error. But it didn't. And perhaps here's why: BoxCoxLambda <- function(z){ b <- MASS:::boxcox.lm(lm(z+1 ~ 1), lambda = seq(-5, 5,

Hi, Firstly, apologies as I have posted this on community.rstudio.com too. I want to optimise a Box-Cox transformation on columns of a matrix (ie, a unique lambda for each column). So I wrote a function that includes the call to MASS::boxcox in order that it can be applied to each column easily. Except that I'm getting an error when calling the function. If I just extract a column of the

Try this for your function: BoxCoxLambda <- function(z){ y <- z b <- boxcox(y + 1 ~ 1,lambda = seq(-5, 5, length.out = 61), plotit = FALSE) b$x[which.max(b$y)] # best lambda } ***I think*** (corrections and clarification strongly welcomed!) that `~` (the formula function) is looking for 'z' in the GlobalEnv, the caller of apply(), and not finding it. It finds

Estimados Le consulto porque estoy intentando presentar unos datos de alguna forma un poco distinta, salir un poco de la costumbre. Primero describo los datos: Suponiendo una secuencia: golpe al auto -> torura de vidrio -> rotura de aciento otro auto golpe al auto -> -> rotura de aciento , a este por alguna causa no se le rompio el vidio o esa información es desconocida.

Hi, I made the attached picture by mocking up three separate plots sort of like how I'd like to make a new plot. Hopefully it will get through to the list. Is there a way to do this directly using par somehow? Or one of the other plotting packages? Basically, multiple larger plot above multiple groups of smaller plots? The smaller plots are just par(mrow=c(2,3)) things, and I can

hi, i am using par(mrow=c(6,6)) function to get 6x6 plots on one screen. the problem that i am having is that the axis tick labels are far away from the ticks and going into previous plots (see attached figure). i need to know how can i reduce the distance between the ticks and their values (y axis values).the part of the code that i am using (after reading in the data) to create the top row is:

...and line interpreter (but it does still show you command line completions on the bottom of the window). The only exception I've found is when there is no character string at all before the opening parenthesis. Then you can type as quickly as you want with no ill effects. -- Mickey Rowe (mrowe at lifesci.ucsb.edu)
