[R] Defining array for nested for.loop.

Hey guys. The idea is I want to create a nested for.loop using pick.a values and m.control and m.sham at trunc1 to trunc6. How would I go about defining an array for this? I am unsure about what to put into length( ). In my last assignment it was a little bit more straightforward since I had:

Pete, Thank you for this example. I recommend using the likert function in the HH package. d2 <- structure(c(1000, 2000, 2500, 5000, 1000, 2000, 3000, 2000, 200, 600, 1000, 900), .Dim = c(4L, 3L), .Dimnames = list(c("1/1/2014", "2/1/2014", "3/1/2014", "4/1/2014"), c("A", "B", "C"))) d2 likert

Re: [R] amqp_connection:open_channel link channel

I am mystified. Your question lacks any context... it is at best off-topic in R-help. The syntax you show does not seem related to R, and if you were to discuss AMQP as it relates to R then I suspect you would need to post in R-devel. -

1. Do not post in HTML -- it gets filtered out or scrambled (although we could probably figure it out anyway if we were so inclined. I am not.). See ?dput to see how to copy and paste in a text format that we can use to easily reconstruct your data structure. 2. You will probably have to more clea
