Renaming columns

Is there a better way to rename columns in a DataFrame than the following code? I could not find any information for renaming columns in the Guide or API doc. In this code, I’m trying to rename columns “Like This” to “like_this”.

slugify = (s) => s.toLowerCase().replace(' ','_').replace('/','_or_')

rawData = 
    DataForge.readFileSync('data.csv')
    .parseCSV({ dynamicTyping: true })

for(let name of rawData.getColumnNames()) {
    let s = rawData.getSeries(name)
    rawData = rawData.dropSeries(name).withSeries(slugify(name), s)
}

You are correct! It should be using Map already. Thanks for leaving feedback and pointing it out.

I’ll leave this issue open until I get it fixed.

Yeah there is! Are you able to use the function renameSeries?

const renamedDf = rawData.renameSeries({ "OldColumnName": "NewColumnName" });

You might be able to use it like this:

let rawData = 
    DataForge.readFileSync('data.csv')
    .parseCSV({ dynamicTyping: true })

let renameSpec = {};

for(let name of rawData.getColumnNames()) {
   renameSpec[name] = slugify(name);
}

rawData = rawData.renameSeries(renameSpec);

Otherwise I’ll have to think about this, seems like there should be a better way to do it!
