Syntax

vo = getvaropts(opts, vars)

Description

The returned object lists how a column is read: its Type, the FillValue used for missing entries, strings treated as missing, and type-specific settings such as the decimal separator for numbers. Change them with setvaropts and pass the modified opts to readtable.

Input arguments

opts

Import options object, such as one made by detectImportOptions or delimitedTextImportOptions.

vars

Variable name, cell array of names, or numeric indices.

Output arguments

vo

A variable-options object (for example NumericVariableImportOptions) for one variable, or a cell array of them for several.

Example

Options of one variable

opts = delimitedTextImportOptions('NumVariables', 2);
opts.VariableNames = {'id', 'score'};
opts = setvartype(opts, 'score', 'double');
v = getvaropts(opts, 'score');
disp(v.Type)
disp(v.FillValue)

double
   NaN
