Unable to Plot using headers.
Hi, You need to tell R where to find them, since they aren't R objects. (You can see all the actual objects with ls().) Two of the many options: with(demand, plot(Qty, Date)) plot(demand$Qty, demand$Date) Sarah On Fri, May 27, 2011 at 2:35 PM, Struckmeier, Nathanael

Hello List! Thank you for your input so far. I have successfully imported my data into R but have hit a snag in plotting. Simple plot commands are unable to find my headers when I try and plot my data on an x/y scatter. My data is a 2 column 8000 row table (saved as .txt file) imported into R.
demand=read.delim("C:\\Documents and Settings\\E066582\\My
Documents\\R\\R-2.13.0\\bin\\demand.txt") First rows with headers are as shown:
demand[1,]
? ? ? ?Date Qty 1 12/31/2006 ? 1 With two columns Date/Qty. I attempted to plot and received an error. My headers were not found as an object in R...maybe I'm missing something, but I was under the impression I didn't need to create each header as an object...
plot(Qty, Date)
Error in plot(Qty, Date) : object 'Qty' not found
plot(Date, Qty)
Error in plot(Date, Qty) : object 'Date' not found What step in plotting am I missing?
