se do.call("[",c(list(xj,i), rep(list(bquote()), length(dim(xj))-1L), list(drop = FALSE))) Would this be possible and work? Thanks! Georg   Gesendet: Freitag, 26. Mai 2023 um 21:05 Uhr Von: "Bert Gunter" An: "Georg Kindermann" Cc: "Rui Barradas" ,

So is this an expected behavior or is it a bug which should be reported somewhere else? Thanks! Georg      Gesendet: Dienstag, 09. Mai 2023 um 19:28 Uhr Von: "Bert Gunter" An: "Georg Kindermann" Cc: "Rui Barradas" , r-help@r-project.org Betreff: Re: [R] data.fra

[R] Why is R making a copy-on-modification after using str?

Dear list members, I was wondering why R is making a copy-on-modification after using str. m <- matrix(1:12, 3) tracemem(m) #[1] "<0x559df861af28>" dim(m) <- 4:3 m[1,1] <- 0L m[] <- 12:1 str(m) # int [1:4, 1:3] 12 11 10 9 8 7 6 5 4 3 ... dim(m) <- 3:4 #Here after str a copy is made #tracemem[0x5
