I have something like this, and want to turn xlabels 45 degrees (it is going to be rather long text):

```
a<-c(1:10)
b<-c(1:10)
c<-c(1:10)
scatterplot3d(a,b,c,
main="3-D Scatterplot",color="blue", pch=19,
type="h", lty.hplot=2, box=F,
scale.y=.5,
lty.grid=1,
lab=c(9,5,1),
xlab="",
ylab="",
zlab="")
```
