00:04:26 Howard Baek: Good to see you again, Olivier
00:11:01 Derek Sollberger (he/him): start
00:18:16 Olivier Leroy: T is not a restricted name unlike TRUE:
00:18:17 Olivier Leroy: > TRUE <-"bob"
Error in TRUE <- "bob" : invalid (do_set) left-hand side to assignment
> T <- "bob"
>
00:22:03 Steffi LaZerte (she/her): nchar()
00:25:34 Olivier Leroy: A reference from War ? :p
00:25:39 Olivier Leroy: Wat
00:26:50 Olivier Leroy: (https://www.destroyallsoftware.com/talks/wat)
00:32:26 Howard Baek: I found a blog post discussing different flavors of NA: https://www.njtierney.com/post/2020/09/17/missing-flavour/
00:32:47 Olivier Leroy: Brb just checking in an other book
00:36:12 Olivier Leroy: > x <- 1L
> is.numeric(x)
[1] TRUE
> y <- 1.4
> is.numeric(y)
[1] TRUE
00:37:20 Olivier Leroy: > x <- 1
> is.double(x)
[1] TRUE
00:39:51 Derek Sollberger (he/him): aside: banker's rounding
00:39:56 Olivier Leroy: > x <- 2.8
> as.integer(x)
[1] 2
00:40:04 Olivier Leroy: (truncated)
00:40:11 Howard Baek: Non-integral numeric values are truncated towards zero (i.e., as.integer(x) equals trunc(x) there)
00:40:29 Howard Baek: I found the above in the help page
00:40:34 Olivier Leroy: Reacted to "I found the above in..." with π

00:44:36 Jo Hardin: also, the integer class is complicated because factor variables are integers⦠sort of

00:52:18 Howard Baek: From the help page:
An array in R can have one, two or more dimensions. It is simply a vector which is stored with additional attributes giving the dimensions (attribute "dim") and optionally names for those dimensions (attribute "dimnames").
A two-dimensional array is the same thing as a matrix.
