[R] Package httr::GET() question

[Roy Mendelssohn - NOAA Federal]

Thanks.  Yes that is what I found out.  We are switching our web service to require strict encoding  (a lot of services got caught when Apache Tomcat made a similar switch)  and are trying to see if it that will break any of our R packages before we make the switch,

As always,  appreciate all the people who took time to respond.

My memory forma number of years back was that I had issues with urlencode from base not being strict.  And of course you don't what to encode twice.
