[R] develop.raw error ( adimpro )

[Cleber N.Borges]

Hello all,
I'm trying to use the adimpro package to read RAW files (image). Make 
readins is OK!
> r <-  read.raw( '20171218_210956.dng', type='RAW', compress=FALSE )
> summary( r )
> ### cut the many lines...
Filter pattern: GR/BG
> extract.info( r )
[1] "GR/B"
> 
To next, develop the raw file using the "develop.raw" function.
But the function returns the error:
>  dr <- develop.raw( r )
Error in dim(mat) <- c(4, 3) :
   dims [product 12] do not match the length of object [0]

My suspicion is that the develop.raw function fails to get the correct 
Bayer's  pattern.
Within the develop.raw function there is a code (below) that will always 
return the pattern as a variable of NULL value

> bayer <- switch(extract.info( r ), RGGB =  1, GRBG = 2, BGGR = 3, GBRG = 4)
> bayer
NULL
> 
Is there anything to do to get around the situation?

Thank you so much
Cleber Borges

ps.: below more details
