Hello my R friends, I am using the below commands in R: attach(Puromycin) Puromycin plot(Puromycin$conc,Puromycin$rate) mm=function(conc,vmax,k) vmax*conc/(k+conc) mm mm1=nls(rate~mm(conc,vmax,k),data=Puromycin,start=c(vmax=50,k=0.05),subset=state==?treated?) mm1 Unfortunately, I receive the below error: Error: unexpected input in "mm1=nls(rate~mm(conc,vmax,k),data=Puromycin,start=c(vmax=50,k=0.05),subset=state==?" How can I fix this error?

You have subset=state==?treated?). You need to change "treated? to "treated". Tho " " are formatted in your example.
