[R-SIG-Mac] Difference between Terminal output and GUI output.

[Joseph Kunkel]

Dear R-sig-Mac, 

I have a problem with output from the R.app GUI which is at odds in part with the Terminal console output which I prefer.  The GUI does debug requests interspersed with the desired output. 

My system is:

  Model Name:	MacBook Pro
  Model Identifier:	MacBookPro10,1
  Processor Name:	Intel Core i7
  Processor Speed:	2.7 GHz
  Number of Processors:	1
  Total Number of Cores:	4
  L2 Cache (per Core):	256 KB
  L3 Cache:	6 MB
  Memory:	16 GB
System Software Overview:
 System Version:	OS X 10.9.4 (13E28)
 Kernel Version:	Darwin 13.3.0

R version 3.1.1 (2014-07-10) -- "Sock it to Me"
Copyright (C) 2014 The R Foundation for Statistical Computing
Platform: x86_64-apple-darwin10.8.0 (64-bit)

R.app GUI 1.65 (6784 Snow Leopard build), S. 

An R-script accesses an array XX which has ...

> attributes(XX)
$dim
[1] 12  3  8

The R-script that gives me the problem:
# GetCL.R
for (i in 1:4) { out<- round(((sum((XX[3,,i]-XX[10,,i])^2))^0.5 + (sum((XX[2,,i]-XX[10,,i])^2))^0.5)/2,3)
	            cat(out,'\n')
	            }

The correct output obtained in Terminal mode is:

> source("GetCL.R")
35.791 
35.811 
44.625 
43.316 

In the GUI I get:

> source("GetCL.R")
debug at GetCL.R#3: out <- round(((sum((XX[3, , i] - XX[10, , i])^2))^0.5 + (sum((XX[2, 
    , i] - XX[10, , i])^2))^0.5)/2, 3)
Browse[2]> 
debug at GetCL.R#4: cat(out, "\n")
Browse[2]> 
35.791 
debug at GetCL.R#3: out <- round(((sum((XX[3, , i] - XX[10, , i])^2))^0.5 + (sum((XX[2, 
    , i] - XX[10, , i])^2))^0.5)/2, 3)
Browse[2]> 
debug at GetCL.R#4: cat(out, "\n")
Browse[2]> 
35.811 
debug at GetCL.R#3: out <- round(((sum((XX[3, , i] - XX[10, , i])^2))^0.5 + (sum((XX[2, 
    , i] - XX[10, , i])^2))^0.5)/2, 3)
Browse[2]> 
debug at GetCL.R#4: cat(out, "\n")
Browse[2]> 
44.625 
debug at GetCL.R#3: out <- round(((sum((XX[3, , i] - XX[10, , i])^2))^0.5 + (sum((XX[2, 
    , i] - XX[10, , i])^2))^0.5)/2, 3)
Browse[2]> 
debug at GetCL.R#4: cat(out, "\n")
Browse[2]> 
43.316

Of course this output gets more tedious if I try to process the entire array by running for i in 1:larger-n.
Is there any way to get rid of these debug and browse messages messages in GUI mode? 
I have never experienced this debug output in my ca. 12+ years of using R intensely.

I just recently upgraded to R version 3.1.1 (2014-07-10) and renewed all my libraries.
