Genstat into R - Randomisation test
..., Induced defence (ID), and
constitutive defence (CD). Since Induced and constitutive defence are
not independant (so called spurious correlation) I should do a
randomisation test. I have a syntax of my supervisor in Genstat, but I
would really like to try this in R.
"data from trade-off.IDCD"
list
variate [nval=1000] slope
calc ID1=ID
graph ID; CD
calc b=corr(ID; CD)
calc slope$[1]=b
"slope$[1] is the correlation before permutating the data"
for i=2...1000
randomize ID1
calc b=corr(CD1; ID1)
calc slope$[i]=b
endfor
