Re: [R] Is this *always* the intended R^2 value for no intercept in lm?

To Thierry; When you omit an intercept you require that the line in multivariate space that represents the ‘predictions’ go through the (0,0,0,…) I.e. the origin. It’s a fairly restrictive requirement. There IS an intercept, even though it’s not explicitly seen in the model. If it’s not required

[R] (no subject)

Hello - I am using the MICE package to impute missing values - the input data are up to six vectors of parallel hourly temperature measurements for Scottish weather stations across a calendar year. None of the vectors have more than 5% NAs as I have filtered ones with more out. Most of the sets wo

Hi Uwe, I can do 1. 1. Add the line if ( length(z <- commandArgs(TRUE)) ) utils::file.edit(z[1]) to the Rprofile.site file; and My Rprofile.site file is: "C:/PROGRA~1/R/R-42~1.2/etc/Rprofile.site" How do I do 2, step-by-step? 2. Edit the registry to associate the .R exten

Re: [R] Associate a .R file with the RGui

Hi Uwe, RGui does have advantages vs. RStudio, and vice-versa. RStudio is much faster than it used to be. I currently have .R files associated with RStudio, i.e. in File Explorer if I double-click on a .R file it opens in the editor in RStudio as an R script. In File Explorer if I right-

Re: [R] Selecting a minimum value of an attribute associated with point values neighboring a given point and assigning it as a new attribute

Whoops ... left out a line in Part 2. Resending with the correction ## PART 2: You can use this code on the real data with f() defined appropriately A <- matrix(0,N,N) v <- 1:N ## get the indices (j,k) where j < k (as columns in a data.frame) idx <- expand.grid(v,v) |> rename(j=Var1,k=Var2) |> fil

Re: [R] Selecting a minimum value of an attribute associated with point values neighboring a given point and assigning it as a new attribute

Hi Tiffany, Here is some code that might help with your problem. I solve a "toy" problem that is conceptually the same. Part 1 sets up my toy problem. You would have to replace Part 1 with your real case. The main point is to define a function f(i, j, data) which returns 0 or 1 depending on whether
