Hello,
I want to perform an lme on a database with this structure:
ID Sequence Temperature Tumour Error
1 5 0 1 8.721872e-08
1 5 0 2 8.695348e-08
1 5 0 3 2.019604e-13
1 5 37 1 2.746476e-01
1 5 37 2 1.580415e-02
1 5 37 3 1.586857e-01
1 2 0 1 8.721872e-08
1 2 0 2 8.695348e-08
1 2 0 3 2.019604e-13
1 2 37 1 2.746476e-01
I try to perform an lme with the lme() function of the lme package
(first I attach the data frame with attach()). This is the code:
lme(Error ~ ID + Sequence + Temperature + Tumour)
If I use this code, I get the following error:
Error in getGroups.data.frame(dataMix, groups) :
Invalid formula for groups
Can anyone help me?
Best,
Dani
