[R] difference between assignment syntax <- vs =

[Thomas Mang]

Hi,

Both operators <- and = can be used to make an assignment. My question 
is: Is there a semantic difference between these two? Some time ago, I 
remember I have read that because of some reason, one should be given 
preference over the other - but I cannot remember the source, nor the 
argument, nor which operator the preferred was.

What is the present state ?
Is still one version better than the other, or is it only a matter of 
taste what to use ?

thanks
Thomas
