I am importing a large csv data file into Mathematica for analysis. The problem is that Mathematica insists on displaying all 2500 rows of data. This is only a small subset of a much larger project. Can I just read the file in and display the header like python and pandas. The reason I'm using Mathematica is that I need the Nonlinear Curve Fitting capability.
rbraw = Import["https://raw.githubusercontent.com/benhowe75/rubidium_hyperfine_414/\master/simple.csv", "Table"]
Nice spectrum.
rbraw = Import["https://raw.githubusercontent.com/benhowe75/rubidium_hyperfine_414/master/simple.csv",
"Dataset",
HeaderLines -> 1];
rbraw[Map[Reverse]][ListPlot[#, PlotRange -> All, ImageSize -> 500] &]
You can work like this: import the data, ending the Import expression with a semicolon so to not display the entire table.
rbraw =
Import["https://raw.githubusercontent.com/benhowe75/rubidium_hyperfine_414/\master/simple.csv", "Dataset",
HeaderLines -> 1];
Then you can use the name of the dataset and specify the elements you want to display with the command. rbraw[1;;10]. This will show the first ten values of the table, the same concept is used for more or less values.
rbraw = Import[(* stuff *)];(note the semicolon!), the output is suppressed. You can then use things likeShort[]orShallow[]to look at an elided version of the data. $\endgroup$ – J.
