    <p>I want to find the location of the script .R files which are used for computation in R. </p> <p>I know that by typing the object function, I will get the code which is running and then I can copy and edit and save it as a new script file and use that.</p> <p>The reason for asking to find the foo.R file is</p> <ol> <li>Curiosity</li> <li>Know what is the algorithm used in the numerical computations</li> <li>More immedietly, the function from <em>stats</em> package I am using, is running results for two of the arguments and not the others and have to figure out how to make it work. Error shown by R implies that there might be some modification required in the script file. </li> </ol> <p>I am looking for a more general answer, if its possible. </p> <p><strong>Edit</strong>: As per the comments so far, here is the code to compute spectrum of a time series using autoregressive methods. The data input is a univariate series.</p> <pre><code>x = ts(data) spec.ar(x, method = "yule-walker") 1 spec.ar(x, method = "burg") 2 </code></pre> <p>command 1 is running ok. command 2 gives the following error. </p> <pre><code>Error in ar.burg.default(x, aic = aic, order.max = order.max, na.action = na.action, : Burg's algorithm only implemented for univariate series </code></pre> <p>I did try specify all the arguments correctly like na.action=na.fail, order.max = NULL etc but the message is the same. Kindly suggest possible solutions.</p> <p>P.S. (This question is posted after searching the library folder where R is installed and zip files which come with packages, manuals, and opening .rdb, .rdx files)</p>

    1. COThe way to find the .R files *does* depend on the specifics of the package you're using (how did you install it, for example).

    2. COI have installed them using the install manager in R and am using packages related to time series analysis. I did not find the script .R files in quite a few that I checked even with the zip or tar files which come with the CRAN package online.

    3. COAs for (3), it's _very_ unlikely that the solution to an error from a function in the **stats** package (which is part of the base R distribution, not an add-on) requires modifying the source code. But that's probably better addressed in a separate question, with the specific information provided.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
