I believe that I may have found a bug in R. The top code sample gives
an error as shown. However, by simply switching which field is
initialized first as in the bottom code sample, it works as expected.
This gives an error:
a <- NULL
a[["field1"]] <- 1
a[["field2"]] <- matrix(c(2,1), 1)
Error in a[["field2"]] <- matrix(c(2, 1), 1) :
more elements supplied than there are to replace
Yet, this works as expected:
a <- NULL
a[["field2"]] <- matrix(c(2,1), 1)
a[["field1"]] <- 1
