title: How to remove certain character from a vector in R
body: <p>I have a vector, for example, <code>c(21,34,"99*",56,"90*", "45*")</code>. I need to clean the data using R by transforming this into a vector without the extra <code>*</code>. The result in this example should be <code>c(21,34,99,56,90,45)</code>.</p>
