POhow an ecdf object can be used inside an R package?

Body
copied!<p>I am trying to build an <code>R</code> package and it has several <em>ecdf</em> objects in it. They have been created by ecdf(some variables such as p1). I put them in a list and save that as <em>rda</em> file in data folder, however when I run the function inside the package (suppose named b1) after installing the package I got the following error:</p> <pre><code>b1(zzz[1,]) (zzz is a data frame and I ran the function on one row of it) Error in fc(p1) : could not find function ".approxfun" </code></pre> <p>fc is a ecdf function stored in the saved list, I called the list by data(list1), and then <code>fc<-list[[1]]</code>, inside the function. </p> <p>I also did data(list1), and when I typed: <code>fc<-list1[[1]]</code>, I can see fc as an ecdf object, but when I type <code>fc(1)</code>, I got the following error:</p> <pre><code>Error in fc(1) : could not find function ".approxfun" </code></pre> <p>If I give the choice to R to choose fc as a function or data, when I used package.skeleton and put fc in mylist, it chooses as a function, and creates fc.R, but it does not run, something like this will be saved in fc.R:</p> <pre><code>fc <- structure(function (v) .approxfun(x, y, v, method, yleft, yright, f), class = c("ecdf", "stepfun", "function"), call = quote(ecdf(yyy$p1))) </code></pre> <p>however the object fc is:</p> <pre><code>Empirical CDF: 4825 unique values with summary <br/> Min. 1st Qu. Median Mean 3rd Qu. Max. <br/> 0.01227 0.03857 0.05602 0.10730 0.15250 0.68020 <br/> </code></pre> <p>I really appreciate any help that I can get. Thank you very much for your time in advance. I think I need to figure it out that how should I save fc for the building package. The stats library version is 3.0.1 (I thought that could be the reason, but do not know.) </p>
