Mapping Geographical Coordinate Data

Dear List,

I have a postcode file containing geographical coordinates but this is 
not in the format of a standard shape file. I list some information 
below;

How can I map this file using R? I?ve tried using the sf package with 
st_multipolygon and st_multilinestring without success.

Any help as to which package and appropriate commands to successfully 
map this data using R will be appreciated.

Kind regards
