Offset function in R

Suppose I have the following code:

ord_reg<- clm(as.factor(y)~log10(x), data=dataframe, link="probit")

Suppose that I want to specify that the probit slope is 1.2. Would this be the correct code:

ord_reg<- clm(as.factor(y)~log10(x)+offset(probit_slope=1.2), data=dataframe, link="probit")

What is the name of the variable for which you want to fix a parameter? Let's pretend it is x2 and you want to fix the parameter to 1.2

ord_reg<- clm(as.factor(y)~log10(x)+offset(x2*1.2), data=dataframe, link="probit")

Ben Bolker suggested you want the log10(x) parameter fixed. In which case, you'd do the following:

ord_reg<- clm(as.factor(y)~offset(log10(x)*1.2), data=dataframe, link="probit")
