NA as names of vector from subscripted matrix == bug ?
Is this a bug?
matrix(1:4,nc=2,dimnames=list(1:2,1:2))[c(1,3)]
1 NA 1 3 It has some annoying consequences, e.g.
median( matrix(1:9,nc=3,dimnames=list(1:3,1:3))[1,,drop=F] )
NA 4
The above was for
Version:
platform = sparc-sun-solaris2.7
arch = sparc
os = solaris2.7
system = sparc, solaris2.7
status =
major = 1
minor = 3.0
year = 2001
month = 06
day = 22
language = R
The behavior seems to differ slightly in 1.3.1.
On Windows 1.3.1
matrix(1:9,nc=3,dimnames=list(1:3,1:3))[ cbind(1:3,1:3) ]
omits the names (as is my preference).
