ellipse.default(): center has no effect

Many thanks for developing ellipse and for putting the source on GitHub! I'm wondering if the addition of argument center is as intended. centre is used on line 27/28

ellipse/R/ellipse.default.R

Line 27 in e41ef76

matrix(c(t * scale[1] * cos(a + d/2) + centre[1], t * scale[2] *

However, there is no previous assignment centre <- center conditional on center being supplied but not centre. Consider

> e1 <- ellipse:::ellipse.default(0.8, center=c(1, 2))
> e2 <- ellipse:::ellipse.default(0.8, center=c(0, 0))
> all.equal(e1, e2)
[1] TRUE

Using centre instead really gives different ellipses.
Note there is a typo in the warning on line 7 (one should be center)

ellipse/R/ellipse.default.R

Line 7 in e41ef76

    
           warning("Specify centre or centre, not both. The value from centre will be used.")

Thanks in advance!

Yes, you're right. I'll fix it.

Now fixed. I'll wait a few days to see if anything else turns up before sending this to CRAN.

Thank you very much!

Just accepted by CRAN. Thanks for the report!
