With regard to Martin's comment about the strength of (base) R:
I have R code I wrote 15+ years ago that has been used regularly ever since
with only a few minor changes needed due to changes in R. Within that code, I
find particularly impressive for its stability a simple custom GUI that uses

Hi,
This array is of type "list" but print() reports otherwise:
a1 <- array(list(1), 2:0)
typeof(a1)
# [1] "list"
a1
# <2 x 1 x 0 array of character>
# [,1]
# [1,]
# [2,]
No such problem with an array of type "logical":
a2 <- array(NA, 2:0)
typeof(a2)
# [1] "logic
