Hello, I am wondering how to get the quotation marks into a variable expression. I can't escape it with the backslash \ ... Example: I can access my data frame via TABLE$"2011-01-02"$columnD Now I want to do this automatically.. (with a for loop).. a <- TABLE b <- " \"2011-01-02\" " c <- "columnD" acessmytable <- paste(a,b,c, sep="$") parse(text="accessmytable") eval(accessmytable) It will return [1] "TABLE$\"2011-01-02\"$close" but I need TABLE$"2011-01-02"$close I highly appreciate your help!
