Possible failure to escape variable names

[rodzam]

Issue: DataExplorer does not properly escape variable names when given as a string in an argument.

Example:

df1 <- tibble(population=c(10,20,30,40,50), `poverty-rate`=c(50,40,30,20,10), `pct-hisp`=c(.2,.5,.3,.2,.6))
plot_scatterplot(df1, by="poverty-rate")

Error:

Error in FUN(X[[i]], ...) : object 'poverty' not found

I expect it's a simple issue where the function isn't properly escaping the variable name (e.g., `poverty-rate`). As an aside, I'd agree that it's bad practice to include mathematical operators in the variable name but sometimes an external dataset will use that nomenclature so we must work with it.

Working with irregular names is not easy, and creates a lot of potential problems. End users should supply appropriate names because it is so much easier to do so. E.g.,

names(df1) <- make.names(names(df1))
plot_scatterplot(df1, by = "poverty.rate")

As a result, I am closing this.
