Hi bbb_aaa,
The format for the input to the function (gantt.info) is a list. As
Sarah mentions, a data frame is a list, so as long as your columns
have the right names and are in the correct order, it should work. As
you probably know, you can import a CSV file into R as a data frame
using read.csv
