I'm trying to concatenate two strings. The first string should look like the following:

a <- paste("//*/a[@href = 'abcd1234.cfmcyc_dt=",eopm, "&orig_id=1234']",sep="")
> a 
 [1] "//*/a[@href = 'abcd1234.cfmcyc_dt=20160731&orig_id=1234']"

Then I want to add the second string which is just a closing parentheses like so:

b <- ")"
c <- noquote(b)
[1] )

I try the following but the double quotes gets moved to the end:

paste(a,c)
"//*/a[@href = 'abcd1234.cfmcyc_dt=20160731&orig_id=1234'])"

I want it to look like this:

"//*/a[@href = 'abcd1234.cfmcyc_dt=20160731&orig_id=1234']")

I tried work with escaping the quotes but I can't seem to get it.

    Why are you doing this? The outer parentheses are only shown because it's a character string. They are not really there. `noquote` is not going to help, btw. If you are trying to assemble a function call with strings, stop and do it the right way. – Rich Scriven Aug 24 '16 at 16:05

Try doing this way:

a <- paste("//*/a[@href = 'abcd1234.cfmcyc_dt=", 'eopm' , "&orig_id=1234']",sep="")
b <- '")'
c <- noquote(b)

Result 

paste(a, c)
[1] "//*/a[@href = 'abcd1234.cfmcyc_dt=eopm&orig_id=1234'] \")"

Try this:

eopm <- 20160731    
a <- paste0("//*/a[@href = 'abcd1234.cfmcyc_dt=",eopm, "&orig_id=1234']")
b <- '")'
c <- noquote(b)
noquote(paste0('"',a,c))

Result:

> noquote(paste0('"',a,c))
[1] "//*/a[@href = 'abcd1234.cfmcyc_dt=20160731&orig_id=1234']")

  • According to what you have posted, your solution doesn't really produces the right answer. – Pj_ Aug 24 '16 at 16:15
  • I edited the answer because i forgot to copy the set of the variable eopm, but it does produce the result – Erick Díaz Aug 24 '16 at 16:41
