How to deal with spaces in my variables?

[Mouna Belaid]

Hello

How are you?

In my table there is this variable " pollution car" and as you notice here there is a space between "pollution" and "car" but while using ggplot2 and typing aes(x=pollution car........)

I don't get what I want as there is a space, what should I do?

Please help me

You can refer to this using backticks, e.g. x$`pollution car` or
aes(`pollution car` = size).

Hi,

my suggestion would be to keep your data tidy and eliminate leading number, spaces and special characters from variable names. This makes the code more robust and transferable.

Please also note that this is a ggplot2 related mailing list and more appropriate venues for these sort of questions exist. A search of the internet using your favorite google search engine may yield relevant results and if not, feel free to post (also general and ggplot2 related) questions to StackOverflow. Note that this site has a powerful search engine with 141000 questions on R. Chances are there's already an answer, somewhere.

Cheers,

Roman

According to a post that I found in stackoverflow using backticks should solve your problem. I tried it, it works.
