title: Standardize data columns in R
body: <p>I have a dataset called <code>spam</code> which contains 58 columns and approximately 3500 rows of data related to spam messages. </p>
  
  <p>I plan on running some linear regression on this dataset in the future, but I'd like to do some pre-processing beforehand and standardize the columns to have zero mean and unit variance. </p>
  
  <p>I've been told the best way to go about this is with R, so I'd like to ask <strong>how can i achieve normalization with R</strong>? I've already got the data properly loaded and I'm just looking for some packages or methods to perform this task.  </p>
