I have a set of data with 2 columns: time, size. There are 20 sets of data. The data is looking at whether the size of a seed affects the time it takes to germinate. How do I then create a numerical variable called 'order' with values 1 to 20 in order to plot a graph or order against time? -- View this message in context: http://r.789695.n4.nabble.com/Order-function-tp4651022.html Sent from the R help mailing list archive at Nabble.com.
Are you asking how to create a variable in each data set so that data set 1 has the idenfier 1 and so on? It's not clear from what you say if you have 20 different data sets (say data frame or file for each ) or if you have one file with the data. As a brute force approach in either case I'd just create a vector of appropriate length and cbind it to the data frame or whatever.

And yes I want the variable 1 to have the identifier 1 etc. And I need to call this variable "order" so I can use it to create an anova table. -- View this message in context: http://r.789695.n4.nabble.com/Order-function-tp4651022p4651198.html Sent from the R help mailing list archive at Nabble.com.
This is not a homework help list and it is even less a homework help list when there is no clear statement of the problem. I'd suggest reading something about how R works -there are some very good tutorials and introductions listed on the R site, and then perhaps coming back here if you have a specific question. http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example John Kane Kingston ON Canada> -----Original Message----- > From: linda_007 at hotmail.co.uk > Sent: Wed, 28 Nov 2012 08:49:42 -0800 (PST) > To: r-help at r-project.org > Subject: Re: [R] Order function > > I have one text file with all the data on there. > > So 20 rows of data.
