[R] problem using ts after tapply

here is a distillation of a problem encountered in transfering some
working code from R-0.63 to R-1.1.0

a1 <- 1:10
b1 <- tapply(a1,a1, sum)
c1 <- ts(b1)
Error in if (NCOL(x) == 1) { : missing value where logical needed

note that the error is returned as the value of calling ts() and is not
automatically displayed

problem seems to be that 
is.array(b1) returns TRUE
yet dim(b1) returns 10

bug or feature or am I missing something?
