Error using ==&gt; evalR at 58 <br>Problem evaluating command source('test.r'). <br>Invoke Error, Dispatch Exception: Object is static; operation not allowed <br><br>Any insight in to this problem would be appreciated. <br><br>Also, I was wondering how (at the Matlab command prompt) to extend a single command across two or more lines so as to be able to write longer R functions using the evalR link from the command line? <br><br>Thanks for the help! <br><br>Smjorvi tag:www.nabble.com,2006:post-13775606 2007-11-15T08:57:20Z 2007-11-15T08:57:20Z tintin_et_milou Hello, <br>I want to automize the calling of a function on VB for different paths.
