splitting a string up
x <- "1041281__2009_08_20_.lev"
I would like to split this string up and only extract the leading numbers.
1041281
to use as a label for a data column in a bigger for loop function to
read in data.
regards,

Multiple Plotting help (lines don't always connect)

), .Dimnames = list(NULL, c("a", "b")))

This is simplified, but Is there an option I am missing that will
force all of the points to be joined by a line?
