Dear R Users,
I am working with gsub for the first time. I am trying to remove some
characters from a string. I have hit the problem where the period is the
shorthand for 'everything' in the R language when what I want to remove is
the actual periods. In the example below, I simply want to remove the
periods as I have removed the comma, but instead the complete string is
wiped out. I would appreciate it if someone could let me know how I
communicate that I want to remove the period verbatim to R.
Many thanks.
