How to send Html using SQL Server db mail
All,
I have a variable called `go` and it has a single quote in the name
column of line 47 that I am trying to get rid of. I have tried using
gsub, but I cannot get the syntax correct to tell R to remove the '
(single quote).

...this got easier. I clicked on the link (in Ubuntu 20.04) and it
downloaded it. From there few problems. `read.csv()` just reads it:
