Hello all,
I am currently trying to recover FAQ data from a mysql database, as the system is
will be shut down soon
and unfortunately the user interface does not support FAQ export.
Below is a data frame FAQ_RAW , what is the method to decode and save or possibly output the $ content?
The $content includes png, jpeg and pdf data.
As a newbie to rStudio, maybe any of you know of some good literature/tutorials on this topic? 
> str(FAQ_RAW)
'data.frame': 2 obs. of 11 variables:
$ id :integer64 78 79
$ faq_id :integer64 61 61
$ filename : chr "SH0051 STAWS NHK sitzt fest.pdf" "image.png"
$ content_size : chr "1172454" "295778"
$ content_type : chr "application/pdf" "image/png; name=\"image.png\""
$ content :List of 2
..$ : raw 25 50 44 46 ...
..$ : raw 89 50 4e 47 ...
$ inlineattachment: int 0 1
$ created : POSIXct, format: "2020-03-18 12:42:12" "2020-03-18 12:42:12"
$ created_by : int 6 6
$ changed : POSIXct, format: "2020-03-18 12:42:12" "2020-03-18 12:42:12"
$ changed_by : int 6 6
