[Rd] How to maintain memory in R extension

2014-11-12 Thread Zheng Da
Hello, I wrote a system to perform data analysis in C++. Now I am integrating it to R. I need to allocate memory for my own C++ data structures, which can't be represented by any R data structures. I create a global hashtable to keep a reference to the C++ data structures. Whenever I allocate one,

Hi, I think you need external pointers: http://cran.r-project.org/doc/manuals/r-release/R-exts.html#External-pointers-and-weak-references The docs also has an example. See more examples from other R packages here: https://github.com/search?q=R_MakeExternalPtr+user%3Acran&type=Code&utf8=%E2%9C%93

[Rd] Problem with build and check

2014-11-12 Thread Therneau, Terry M., Ph.D.
I am getting failure of build and check, for an Rd file that has a long argument list. Guess diagnosis: a quoted string beyond a certain point in the argument list is fatal. Example: Use the function below, create an Rd file for it with prompt(). Move the .Rd file to the man directory (no ne

I certainly have longer argument lists with no problem. More likely the Rd file needs special consideration for %. Paul On 11/12/2014 02:11 PM, Therneau, Terry M., Ph.D. wrote: I am getting failure of build and check, for an Rd file that has a long argument list. Guess diagnosis: a quoted stri

'Writing R Extensions', section 2.1 Rd format, says" Comments run from a percent symbol % to the end of the line in all types of text (as on the first line of the load example). Because backslashes, braces and percent symbols have special meaning, to enter them into text sometimes requires escape
