Running the following analysis gives as a result kukot vs. kisut.

aikaero <- -27.5+5*(0:10)
frekvenssi.m <- c(0,1,15,37,53,45,23,18,4,1,1)
frekvenssi.n <- c(2,8,12,19,33,47,42,15,2,1,0)
win.graph()
aikaero <- rep(c(aikaero,aikaero), c(frekvenssi.m,frekvenssi.n))
 a.ero <- data.frame(aikaero,
            sukupuoli=rep(c("kukot","kisut"),
                          c(sum(frekvenssi.m),sum(frekvenssi.n))))
    qq(sukupuoli ~ aikaero, data=a.ero)

However, running the following analysis, gives miehet vs. miehet.

 aikaero <- -27.5+5*(0:10)
 frekvenssi.m <- c(0,1,15,37,53,45,23,18,4,1,1)
 frekvenssi.n <- c(2,8,12,19,33,47,42,15,2,1,0)
 win.graph()
 aikaero <- rep(c(aikaero,aikaero), c(frekvenssi.m,frekvenssi.n))
 a.ero <- data.frame(aikaero,
        sukupuoli=rep(c("miehet","naiset"),
                      c(sum(frekvenssi.m),sum(frekvenssi.n))))
     qq(sukupuoli ~ aikaero, data=a.ero)

This seems to happen everytime "sukupuoli" contains one variable name, which
starts with a letter "n". If both names start with "n" or other letters the
results is miehet vs naiset as expected.

So this works fine:

a.ero <- data.frame(aikaero,
        sukupuoli=rep(c("nisset","naiset"),
                      c(sum(frekvenssi.m),sum(frekvenssi.n))))
     qq(sukupuoli ~ aikaero, data=a.ero)

And this also:

a.ero <- data.frame(aikaero,
        sukupuoli=rep(c("miehet","maiset"),
                      c(sum(frekvenssi.m),sum(frekvenssi.n))))
     qq(sukupuoli ~ aikaero, data=a.ero)

Where's the problem?
