I'm a tyro at R, but it's obvious here that the line pdf("/tmp/graph/x.pdf") has the intended file name string 'x' embedded with the literal string enclosed in quotation marks. Obviously he needs "/tmp/graph/" string concatenated with x and then ".pdf". I would suggest a fix, but I am unable to find in the documentation how to concatenate two strings into a single string. So I will amplify gecko951's question to include "How you you concatenate two strings in R?". I.e., x<-"abc" y<-"def" What operator or function returns "abcdef" as a result?
