This is a simple R script that dumps all function names from a specified package for easy inclusion into filetypes.R. This is useful if you use a package frequently that is not shipped with base R.

package_dump.r

package_dump <- function(name, file = NA, ...)
{
    require(name)
    if(is.na(file)) file <- paste(name, "dump", sep = ".")
    cat(ls(paste("package", name, sep = ":")), file = file, ...)
}

By default the function will save the list as a space separated file named after the package with a “.dump” extension, but this can be modified with the file argument. From there, simply copy and paste the list into filetypes.R in your geany configuration directory.
