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?
Thanks.
