abind errors informatively

Code
  abind(a, b)
Condition
  Error in `abind()`:
  ! all <greta_array>s must have the same dimensions except on the `along` dimension
  However, dimension 1 had varying sizes: 5 and 1

Code
  abind(a, c, along = 5)
Condition
  Error in `abind()`:
  ! `along` must be between 0 and 4
  Instead `along` was 5

assign errors on variable greta arrays

Code
  z[1] <- 3
Condition
  Error in `[<-`:
  ! cannot replace values in a variable <greta_array>

rbind and cbind give informative error messages

Code
  rbind(a, b)
Condition
  Error in `rbind()`:
  ! all <greta_array>s must be have the same number of columns

Code
  cbind(a, b)
Condition
  Error in `cbind()`:
  ! all <greta_array>s must be have the same number of rows

replacement gives informative error messages

Code
  x[1:2, , 1] <- seq_len(3)
Condition
  Error in `[<-`:
  ! number of items to replace is not a multiple of replacement length

Code
  x[1, 1, 3] <- 1
Condition
  Error:
  ! subscript out of bounds

Code
  x[3] <- 1
Condition
  Error in `[<-`:
  ! subscript out of bounds

extraction gives informative error messages

Code
  x[1, 1, 3]
Condition
  Error:
  ! subscript out of bounds

Code
  x[3]
Condition
  Error in `x[3]`:
  ! subscript out of bounds

dim<- errors as expected

Code
  dim(x) <- pi[0]
Condition
  Error in `dim<-`:
  ! length-0 dimension vector is invalid

Code
  dim(x) <- c(1, NA)
Condition
  Error in `dim<-`:
  ! the dims contain missing values

Code
  dim(x) <- c(1, -1)
Condition
  Error in `dim<-`:
  ! the dims contain negative values:
  `dim(x)` returns 3 and 4

Code
  dim(x) <- 13
Condition
  Error in `dim<-`:
  ! dims [product 13] do not match the length of object [12]
