R - document () crashes. Error in if (pkg $ package == "devtools") {: argument is 0

Question

UPDATE

I have completed the package and posted it online at https://github.com/iembry-USGS/ie2misc .

Since the error message in the original message did not help, I tried to perform the oxygenation of the package to make sure that it would work or not. Following are the commands and error message.

library(roxygen2)
roxygenize(".", roclets = "rd")

# First time using roxygen2. Upgrading automatically...
# Error in parse(n = -1, file = file, srcfile = NULL,
# keep.source = FALSE) : 
# 1:1: unexpected input
# 1:  
^

I assume that unexpected input refers to a character, but I don't know which file has the corresponding character.

Any help would be helpful.

Thanks.

UPDATE End

I am working on creating a package containing 3 functions. I managed to create 3 other packages using 1 function, but not with this package.
