Is there a simple way to convert data in a dataframe from fraction to decimal format? I have a column of data that that's been recorded as a fraction: Levels: 1/2 1/3 1/4 1/5 1/8 2/3 Is there a quick way to convert it to .5 .333 25 .2 .125 .67?

Here's a way I've done that in the past. <pre class="prettyprint"><code>> frac <- c("1/2","1/3","1/4","1/5","1/8","2/3") > sapply(frac, function(x) eval(parse(text=x))) 1/2 1/3 1/4 1/5 1/8 2/3 0.5000000 0.3333333 0.2500000 0.2000000 0.1250000 0.6666667 </code></pre>

      1/2       1/3       1/4       1/5       1/8       2/3 
0.5000000 0.3333333 0.2500000 0.2000000 0.1250000 0.6666667
