[R] For Loop Syntax
Hi there,
Just wondering if someone can help me with the correct syntax to use
with for loops?
I have split my original file by count, wish to first of all assign
new tables based on the splits. Then I just want to create a new
variable. Please see code below.
This code works outside of a loop so I am just trying to code so I don't
have to repeat numerous times.
Many thanks in advance,
Bronagh
A2 = split(A1,A1$count)
for(i in 1:10){
trial[i] - data.frame(A2$`i`)
trial[i]$BLD[i] - triali$BLD
trial[i]$count - triali$BLD - NULL
}

[R] Array

[R] Running Scripting on Linux Machine
Hi all, I am new to using R on a Linux machine I have a few questions on set-up. If anyone has experience in this area any advice would be greatly appreciated. - When I open R I have the option to do the following: o 'Run in Terminal' o 'Display' o 'Cancel' o 'Run' - My only option to open a window such as we find in the Windows version is to choose 'Run in Terminal'. - I really want to run a script where I can run sections of the code each time. - As we know in Windows we have the option to 'Open New Script' from here can choose 'Run line or Selection' - In this version I can indeed save a script open with 'Emacs', 'KWrite' OR 'Kate'. - But the only way I can run this script is to call the whole script using the source() function. - Does anyone know how I can implement a script that I can run as in the Windows version, whereby I can run one line at a time if I wish for testing purposes?

[R] Running Edit() or Fix() on Linux Machine
Hi all, As I am new to using R on a Linux machine I have another question if that's ok. I am trying to use the fix() or edit() function on this Linux machine but I get the following error message: Error in dataentry(datalist, modes) : invalid device In addition: Warning message: In edit.data.frame(get(subx,envir=parent),title = subx, ...) : Unable to create fontset -*-fixed-medium-r-*-*-*-120-*-*-*-*-*-* It seems that I am trying to use an invalid device? Or I don't have the correct fonset? Has anyone else come across the same issue? And if so, how did you manage to resolve it? Any help would be greatly appreciated.

Re: [R] Running Scripting on Linux Machine
Hi Gavin, I downloaded ESS can now see a buffer named '*ESS*' in my EMACS script file. To start an ESS process I followed the notes in the documentation: 1. To start an S session on Unix or on Windows when you use the Cygwin bash shell, simply type M-x S RET. 2. S will then (by default) ask the question 3. S starting data directory? 4. Enter the name of the directory you wish to start S from (that is, the directory you would have cd'd to before starting S from the shell). This directory should have a '.Data' subdirectory. 5. You will then be popped into a buffer with name '*S*' which will be used for interacting with the ESS process, and you can start entering commands. I can open R via step 1, but step 2 does not then happen. Any advice on how I go about opening the ESS for working on?
