I want to export a dataframe's column classes to a list so that I can
reinstantiate the dataframe from a CSV file in the future. (I know
about save(), which I'm using in addition to this).
what I want to do is the following:
col_classes = get_col_classes(myframe);
... time passes, R gets closed, etc ...
col_classes = read.csv("column_classes")
new_myframe = read.csv("myfile.csv", colClasses = col_classes)
My question is how to construct the "get_col_classes()" function above.
Any thoughts are greatly appreciated!
