My copy shows the following in the example section: ## Not run: ## To write a CSV file for input to Excel one might use write.table(x, file = "foo.csv", sep = ",", col.names = NA) ## and to read this file back into R one needs read.table("file.csv", header = TRUE, sep = ",", row.names=1) ## End(Not run) The filename must be the same in the read.table call in order to read the file back into R. ---------------------------------------------------------- SIGSIG -- signature too long (core dumped)
