Re: [R] How important is set.seed

way to address this is to characterize the distribution of model outcomes from different runs with different random seeds. Examine that characterization and hope for understanding. Tim From: Bert Gunter Sent: Tuesday, March 22, 2022 2:03 PM To: Ebert,Timothy Aaron Cc: Neha gupta ; r-help@r

Re: [R] R Code Execution taking forever

1) Does it run perfectly with num_tirals_6 <- 100 ? 2) Rework the code to remove as much as possible from loops. Renaming column names each time through the loop seems pointless. Is the nested for loops converting the dice roll to person name necessary within the while loo

Re: [R] Confusing fori or ifelse result in matrix manipulation

A <- matrix(1:9,ncol=3) x <- c(0,1,0) M <- matrix(ncol=3,nrow=3) M<-A for(i in 1:3) { if(x[i]){ M[,i] <-0 } } } M The outcome you want is to set all of the middle column values to zero. So I used x as a logical in an if test and when true everything in that column is set to zero. Y

Re: [R] Convert one rectangle into two rectangles

One thought was that these were farm fields in satellite images. I just had no clue why one would subdivide them. Maybe a training and testing portion of these polygons? At a few dozen meters the curvature might be negligible on a sufficiently large spheroid. If 45-55% split is approximate then

Re: [R] Is there a canonical way to pronounce CRAN?

It would be nice in some ways if everyone would pronounce the same word in the same way, but then we could not argue over the correct pronunciation of words like tomato or aluminium/aluminum. I think of cran as "Kran". While I had German in high school I didnn't remember the German word for cran
