One of the other things the output does is (wisely) truncate the middle of a long array when printing. But also sometimes, if I have a DataFrame with 60 columns and do names(df) I want all 60 names so I can scroll through them.
Quick & dirty would be:
The semi-colon is so you also don’t print the result of map which is one nothing for evey element
You don’t need to worry about row vs column vectors in Julia as you do in Matlab. A Julia Vector is neither a row nor a column because it is truly 1-Dimensional and does not know about any other dimensions to orient itself against.
If you slice a Matrix in Julia in either direction, the result is a 1D Vector that forgets about its previous orientation.
DataFrames.jl has a DataFrameRow type. It is used to preserve extra information about the data frame that would be lost if the data was presented as a Vector. For example, it has the special ability to be indexed by column name.
