R help - Sep 2013 - exchange of axis labels in qqnorm function

Hello all,

Are there a reason for this behaviour in qqnorm function?
(the exchange of axis labels )

#Default
 > qqnorm(x, xlab='X Axis', ylab='Y  Axis', datax=TRUE )

Thanks for any explanation.

Hello,

That's documented behavior. From the help page for ?qqnorm:

datax: logical. Should data values be on the x-axis?

(Try it without renaming the axis and it makes more sense.)


Hope this helps,
