interactive brokers - IBrokers R - reqId returns error -

i try use following code, got stuck on reqid. gives error: could not find function "reqid"

then tried

r <- ibrokers:::reqid(t,numid =1) 

but still got error

error in get(name, envir = asnamespace(pkg), inherits = false) :
object 'reqid' not found

if changed reqid reqids, it's not return error. try run ibrokers:::reqfundamentaldata line , return null

any idea how getfundamentaldata work?

here code:

library(ibrokers) #t <- ibgconnect() - didn't work tws <- twsconnect()`enter code here` isconnected(tws) reqcurrenttime(tws) c <- twsequity("ibm") # x <- ibrokers:::reqfundamentaldata(tws,c) - line didn't work # r <- reqids(tws,numid =1) - line didn't work r <- reqids(tws,numid =1) x <- ibrokers:::reqfundamentaldata(tws,reqid = r, contract = c, reporttype = "reportfinsummary")
