> str(y) #toy vector, subset of larger vector in a dataframe of ~4,600 rows.
chr [1:5] "$1,000.00 " "$1,000.00 " "$1,000.00 " "$2,600.00 " "$2,600.00 “
y is a subset of a column in a dataframe that’s too big to post. I tried the
commands listed here on the dataframe and it didn’t work. So I’m using a small
subset to find out where my error is. It’s being a PITA, and I’m trying to
solve it. What I want is a vector of numbers: 1000, 1000, 1000, 2600, 2,600.
What I’ve tried:
> y
[1] "$1,000.00 " "$1,000.00 " "$1,000.00 " "$2,600.00 " "$2,600.00 "
> gsub("$", "", y)
[1] "$1,000.00 " "$1,000.00 " "$1,000.00 " "$2,600.00 " "$2,600.00 “ # no
change. Why?
> gsub(".00", "", y) # note: that’s dot zero zero, replace with “"
[1] "$10 " "$10 " "$10 " "$2, " "$2, “ #WTF?
I’ve also tried sapply and apply, but haven’t yet tried a loop. (These were
done in desperation; gsub ought to work the way the help says.) I’ve tried lots
more than is listed here, over and over, with no results. I’d be grateful for
any guidance you can provide.
Thanks in advance,
Jim Plante
