How do I assign a value label to a string?
显示 更早的评论
Im trying to assign values to 3 string variables of gender so that:
0=nonbinary
1=female
2=male
This is so that im able to add it as a predictor in a simple regression.
However, im not sure how to do this.

It's not clear what you're trying to do but I think you have a list of stings and you're trying to assign them a numerical value according to their group.
gender = {'f' 'm' 'n' 'f' 'm' 'n'};
genderGroup = findgroups(gender); %matlab 2015b or later
If you'd like to assign specific values,
genderGroup = nan(size(gender));
genderGroup(strcmp(gender, 'f')) = 1;
genderGroup(strcmp(gender, 'm')) = 2;
genderGroup(strcmp(gender, 'n')) = 0;
However, if this group variable is used as a category in a regression function, you probably don't have to use numerical categories. You might be able to just convert your strings to categories.
categorical(gender)
