Thank you Greg
I will likely go with a list of data frames as each data frame will
represent independent entities and as the syntax will probably be
better that way.
I did find it puzzling that multidimensional data frame or the ability
to hold a vector in a cell of a data frame was not added in
If all your data is numeric then you can use an array instead of a data
frame and arrays can easily be 3, 4, or higher dimensional. Or you can use
a data frame with a column each for x, y, z, and time; with possible other
columns representing groups or other attributes, essentially a 3
dimensional
Dear all,
I have a problem where I must represent points with XYZ coordinates
changing over time. I will do a number of operations on this data such as
calculating the YZ-projection distance of the points to the origin over
time, the frequency spectrum of the X-T data etc. I am trying to find a
go
