R devel - Oct 2009 - str() gives odd looking output on complex vectors that are not purely imaginary (PR#13985)

Try this:

x <- rnorm(25)
y <- rnorm(25)*1i
z <- x+y
str(z)
str(y)

When I try this, I see the following:
> str(z)
 cplx [1:25] 0.0102+ 0.9463-1 -1.1111+ ...
> str(y)
 cplx [1:25] 0+0.0975i 0-1.5060i 0+0.4071i ...

I see this in 2.9.2 and in the alpha build of 2.10.0:

Thank you, Rich.

That is indeed a bug in  prettyNum(*, drop0trailing=TRUE)
which I will fix  ASAP.
