R help - Apr 2009 - paste(" /" ") and paste(" /' ")

I wish to write  "" using paste(), but


 >
paste("\"","Hola","\"",sep="")
[1] "\"Hola\""
 >


while the same approach works with ''
 >
paste("\'","Hola","\'",sep="")
[1] "'Hola'"


why this difference? how could I do it to get "Hola" ?

Thanks

Agus

paste() doesn't write anything, it constructs character vectors.  It is 
the auto-printing that is adding the backslashes.  Use cat() to write 
things without them:

 >
cat(paste("\"","Hola","\"",sep=""))
"Hola"

In fact, cat() is flexible and you could just use

cat("\"","Hola","\"",sep="")

print() puts double quotes around strings when it prints them; that 
means it needs backslash escapes on double quotes within the string, but 
single quotes are fine.
Your vector did contain "Hola", but print() escaped the quotes.
