Examples

# NOT RUN {
start <- Sys.time()
openPage()

app <- getPage()
time <- Sys.time()

app$openPage(FALSE)
app$openPage(FALSE)

print(getSessionIds())

# No sessions will be closed
closeSession(old = Sys.time() - start)
print(getSessionIds())

# One session (the one that has been opened first) will be closed
closeSession(old = Sys.time() - time)
print(getSessionIds())

time <- Sys.time()
sendCommand("jrc.sendCommand('print(\"Hi!\")')", sessionId = getSessionIds()[1],  wait = 3)
