No. las is a parameter in base graphics ?par. It was simply ignored here:
 xyplot(y~1,scales=list(rot=45), las=1)

differently, change it manually. See the colorkey details in ?levelplot
(also can help with your next thread on positioning). One obvious way is to
add white spaces:
levelplot(matrix(seq(4,120,l=9),3,3))
# or
levelplot(matrix(seq(4,120,l=9),3,3),colorkey=list(at=seq(0,120,20),labels=c('
0',' 20',' 40',' 60',' 80','100','120')))

(If your mail client gobbled them, in the above labels, 0 has two white
spaces before it, 20 has 1 white space, etc.)
