Instrument in rddtools

Chiara.M
Hello!
I have encountered some problems in implementing the function "rdd_reg_lm" (for the fuzzy case) in the rddtools R package. By looking at the function, I understood that an IV regression is actually implemented automatically by the function but I did not understand where to specify the instrument to be used to clear my treatment variable from endogeneity. The command I used to perform the regression is the following:

rdd_reg_lm(rdd_object=rdd_gr, covar.opt = list(strategy = "include"),  order = 4)

where rdd_gr is defined as:

rdd_gr <- rdd_data(x= GDPpc_rel, y= GR.rate, data=data.complete1, covar=Z0, cutpoint = 0.75, z= Treat)

Any help would be very appreciated!
