Edit code in Rstudio

Dear Friend,
When i want to edit one of ligne, i cannot make it easy, each time i should copy/past in text file then edit,
plot(sp500$Adj Close~sp500$Date,type="l",main="S&P500 Evolution",xlab="Date",ylab = "S&P500 Price",col="blue")
so in next step i just want to change for example the name of my second time series, to plot my second,
is there any solution to edit easly my code ?????
