Varun,
If you type dbeta at the command line you get the R source, which in this case
tells you that the code is calling a compiled source. This is indicated by the
line <bytecode: 0x7fc3bb1b84e0>
See the following.
> dbeta
function (x, shape1, shape2, ncp = 0, log = FALSE)
{
if (missing(ncp))
.Call(C_dbeta, x, shape1, shape2, log)
else .Call(C_dnbeta, x, shape1, shape2, ncp, log)
}
<bytecode: 0x7fc3bb1b84e0>
<environment: namespace:stats>
Compiled code in a package
If you want to view compiled code in a package, you will need to
download/unpack the package source. The installed binaries are not sufficient.
A package's source code is available from the same CRAN (or CRAN compatible)
repository that the package was originally installed from. The
download.packages() function can get the package source for you.
