[R] A simple For-Loop doesn't work

Hello, my name is Nick and I'm working on a project. I'm having trouble with building a simple for-loop. In this loop I want to read csv files, perform a corr function and save it to a pdf file. I tried to solve this problem by looking for solutions online but couldn't figure it out. Could you als

Re: [R] Is RcppOctave package available for Mac to install?

Hi David, Thanks for the detail information. I think I will probably work in Octave instead, and fix the problem when I have a little more time. Mike On Sat, Mar 14, 2015 at 2:13 AM, David Winsemius wrote: > > > On Mar 13, 2015, at 11:50 PM, C W wrote: > > > > Hi everyone, > > > > When I tri

While answering a question, I believe it's acceptable (even encouraged) to cite a relevant book, even if it's yours ;-) Spencer On 3/14/2015 9:53 AM, Martin Maechler wrote: John Kane on Fri, 13 Mar 2015 06:16:19 -0800 writes: > I have the feeling that this was discuss

Thanks for the reply. The results of str() are indeed the same. Is there anything else I can check that might explain the difference? > str(phyl_tree) List of 4 $ edge : int [1:15, 1:2] 10 11 12 13 14 14 13 12 15 15 ... $ Nnode : int 7 $ tip.label : chr [1:9] "Heliantheae" "Eupatori

Re: [R] graphs

I suspect that this does look a bit easier to interpret. It certainly beats 68 lines on one graph. Still it's a lot of individual subplots. What I was suggesting was grouping all NASS, HASS, etc. together and graphing each so that you get several lines per subplot. I don't know if this makes se

Re: [R] Help with Programmin-1 submission.

Gary, First off, I doubt anyone here will really be able to help you with a question which is, basically, "How do I submit the R code that I've worked on to my college as an answer to a programming assignment". Unless by chance someone else here happens to be taking that course and knows how to. I

Re: [R] Help with Programmin-1 submission.

Hi Gary, We have no idea what you're talking about. This is the general world-wide R-help group; you need to ask on a forum specific to your course. This group doesn't help with homework anyway, and this is a problem with your course's stuff, not a general R question. Sarah On Friday, March 1

Help. First of all, I admit being a noob when it comes to dealing with R and Git-hub (but not new to programming[embedded mostly]). That being said, this first programming submission with this course is giving me fits. I have the first part of the assignment done, loaded the "submit" sourc
