Hello,

I am having a data set with a mixed of positive and positive number.

Can I use table() command to give me an output of how many data that have negative values and how many have positive value?

I tried one and I have an error message.

```
> table(final_df$Gross_MarginDollars_Percentage(which[final_df$Gross_MarginDollars_Percentage < '0'],))
Error in table(final_df$Gross_MarginDollars_Percentage(which[final_df$Gross_MarginDollars_Percentage < :
attempt to apply non-function
```
