Getting the name of a data frame

Question

I am writing a wrapper function for plotting several data frames:

gf <- function(dataframe){
  ggplot(dataframe, aes(x=Date, y=Close)) + 
  geom_point() + 
  ggtitle(nameofdataframe))

and I cannot figure out the last part, how to get the name of the data frame as a variable to use in ggtitle(). Please help.

Answer 1

This will do it:

ggtitle(deparse(substitute(dataframe)))

deparse() converts the variable name to a character string, substitute() lets you use it in the plot.
