Re placing a "+" in a string
Here are a few ways:
gsub("[+]", "K", "8.00+00")
gsub("\\+", "K", "8.00+00")
gsub("+", "K", "8.00+00", fixed = TRUE)
Note that with gsubfn you can replace several at once as
it is like gsubfn but can take a replacement translation list:
library(gsubfn)
gsubfn(".", list("+" = " plus", "0" = " zero"), "8.00+00")
# gives this: "8. zero zero plus zero zero"

I know this is easy, but I am stumped:
gsub("0","K","8.00+00")
[1] "8.KK+KK"
gsub("+","K","8.00+00")
Error in gsub("+", "K", "8.00+00") : invalid regular expression '+'
In addition: Warning message:
In gsub("+", "K", "8.00+00") :
?regcomp error: ?'Invalid preceding regular expression'
I don't understand the error message. How do I go about replacing the "+" in
the string "8.00+00" with another character?
