I am having some trouble figuring out exactly how to organize data points to be used with the Data Analysis Assistant in Worksheet Mode. I initially extracted the expression sequence of data points from the data structure generated by the plot command (an ordinary 2D plot of a function); I then put the expression sequence in a list and put that in a Vector, and was successfully able to look at the data with the Assistant. I'd like to use my own data points (i.e., from Physics labs, etc.), but I don't know what type of data structure to use. The Assistant tells me to put them in either a Vector or an Array, and I've tried both; I get an error indicating that the order (or dimension) of the Curves structure cannot be found (or something to that effect). I'm sure that I'm missing something very simple, but I'm tired, and don't feel like messing with it anymore, so I figured I would make a post. Thanks a lot for any suggestions.
