Accepted Answer

The problem is that R does not evaluate any expression withing the quotes - it is just printing the string you defined. There are multiple ways around it. For example, you can use the `sprintf` function (untested because you do not provide a reproducible example): ``` cat(sprintf(" ", df$timeStamp, df$Price)) ```
