Hey everyone,
I am trying to remove all the NaNs from an imported table with readtable() (.xlsx file).
i've tried using isnan() but without success.
assuming all i have right now is:
R = readtable('blabla')
how can i remove the NaNs and keep the save the new table?
  • table looks like this:
thanks for the help!

See if the rmmissing function (introduced in R2016b) will do what you want.

thanks for the quick reply
rmmissing(R) is returning a 0x28 table containing no data, maybe im doing it wrong?
%% Import Data & Edit
R = readtable('Cruise_Chem_1975-2021excel.xlsx');
Y = rmmissing(R);
Y=0x28 empty table

My pleasure!
I don’t have the data, so I can’t provide specific help on it. There may be NaN values in the 17 columns that did not make it into the image that have NaN or other missing values, and rmmissing will remove those rows.
Perhaps instead:
Re = R(1:2:end,:)
will do what you want.
That will create ‘Re’ (‘R’ edited) as ‘R’ with the even-numbered rows removed.

You might try using the "MissingRule" option set to "omitrow" in readtable:
R = readtable('blabla', 'MissingRule', 'omitrow');
