I conducted an event study in R for multiple firms having different event dates. However, i am unable to print the results in a loop. This is the code i used, if anyone has an idea that can help me print the results in a loop please kindly share. Thank you.
a = list()
for (i in 1:NROW(trial)) {
firm =loop[i,1]
event.date =loop[i,2]
index =loop[i,3]
a[[i]] =
evReturn(y=trial, firm = firm, event.date=event.date, y.date="date",
index= index, event.win = 5, est.win= 250, digits=4)
print (a[[i]]$result)
}
