I have a dataframe of 2 columns, my values and the standard error.
What I want is to plot a line with my values and then add the standard error as a shaded area around my line.
I do not even know how to start as most of the examples use the geom_ribbon and not an existing column.
I am really confused, is it even possible to plot a shaded area based on an existing column? (any suggestions of tutorials or demos are welcomed!)
