I have entered in code to plot a graph, but when I press Enter to execute the graph, it does not plot the graph. Rather, +
symbols appear every time I press Enter to execute the command and plot the code.
Now there is a long column of +
symbols in my R consoles.
Why is this happening and what can I do to prevent this from happening?
If a plus sign ("+") appears while in the console, it means that R is wanting you to enter some additional information. Press escape ("esc") and hit return to get back to the ">" prompt.
The console window (in RStudio, the bottom left panel) is the place where R is waiting for you to tell it what to do, and where it will show the results of a command. You can type commands directly into the console, but they will be forgotten when you close the session.
The console pane in RStudio is the place where commands written in the R language can be typed and executed immediately by the computer. It is also where the results will be shown for commands that have been executed.
In the terminal, the “normal” way is Control + C – the “cancel” key combination. In the graphical R application and in RStudio, it's Escape .
Now there is a long column of + symbols in my R consoles. Why is this happening and what can I do to prevent this from happening? Show activity on this post. The prompt has + because it signifies that the prompt is expecting more from the line of code, a sort of continuation.

The R prompt shows a plus sign and no result is returned. The reason for this is that we didn’t properly close the function call with closed parentheses (i.e. “)”). In this example this might look obvious, but in practice this is a very typical problem when it comes to more complex user-defined functions or to if and else statements.
That is, when you pressed Enter without completing the R expression that you were typing. This is the case in all R IDEs (R GUI, Architect, etc.), not just RStudio. The value that is printed is a global option: you can retrieve it using getOption ("continue") and change it with the options function.
The prompt has +
because it signifies that the prompt is expecting more from the line of code, a sort of continuation. This may be because you forgot to close something so the prompt expects the closing side. For example, say you forgot to close a string like so:
> "
+
+
Here, I entered a double-quote into the prompt and kept on pressing Enter. There is a missing double-quote to tell the prompt I've ended the string literal, so the prompt expects another double-quote. Once you enter the double quote the prompt will stop expecting it. For example:
> "
+
+ "
[1] "\n\n"
This is standard on all command prompts, to expect more code if something isn't ended properly, like the string literal above. Check your code to make sure you've closed all opening quotes, symbols, etc, so the prompt doesn't expect it and your code executes correctly.
The ways of exiting the prompt when this happens are:
