I found your specification quite vague. What did you mean by a "data file" -- a data frame in R? -- a file in the file system?
I may be completely wrong here, but another possibility is that you read your data into an R data.frame via, e.g. read.table() or read.csv(), but failed to specify the check.names = FALSE, argument. This would cause a column named "x/y" in your original table to be given the name "x.y" in R, as "x/y" is not a syntactically valid name. See ?make.names for details. As others have already said, enclosing non-syntactically valid names in back ticks usually works (maybe always works??). So for example: z<-data.frame (`a/b` = 1:5, y = 1:5, check.names = FALSE) plot(y ~ `a/b`, data = z) ## produces desired plot with correct label z ## yields: a/b y 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5 Of course, ignore if this is all irrelevant.
