This is my thought process of what the loop needs to do but I cant get the
correct loop.
X1=Day[Participant=="1"]
Y1=DrugLevel[Participant=="1"]
Coeffs=function(X1,Y1)
{
lmfirst=lm(Y1~X1)
lmfirst$coefficients
}
Coeffs(X1,Y1)
# output slope and intercept here
# do same for the next participant
X2=Day[Participant=="2"]
Y2=DrugLevel[Participant=="2"]
Coeffs=function(X2,Y2)
{
lmfirst=lm(Y2~X2)
lmfirst$coefficients
}
Coeffs(X2,Y2)
# output slope and in...
