How to get R standard output

[#1]

When I submit R Code via JSL, the R console standard output (stdout) displays in the JMP log.  Is there a way to capture that information in a text string?  I know I can redirect the stdout from R to a file (using the sink() function) and then get the file contents in a JMP variable with some JSL, but I'd rather not have to use an intermediate step like that.

Example;  

names default to here(1);

R Init();

dt=open("$SAMPLE_DATA/Cars.jmp");
R Send(dt);

R Submit(
	"
	summary(lm(formula=Chest.decel ~ Wt, data=dt))
	"
);

RTerm();

This output shows in the log file

Call:
lm(formula = Chest.decel ~ Wt, data = dt)

Residuals:
    Min      1Q  Median      3Q     Max 
-17.931  -6.650  -1.482   5.593  44.232 

Coefficients:
             Estimate Std. Error t value Pr(>|t|)    
(Intercept) 3.853e+01  2.440e+00  15.792  < 2e-16 ***
Wt          3.354e-03  8.135e-04   4.123  4.7e-05 ***
---
Signif. codes:  0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1

Residual standard error: 9.367 on 339 degrees of freedom
  (11 observations deleted due to missingness)
Multiple R-squared:  0.04776,	Adjusted R-squared:  0.04495 
F-statistic:    17 on 1 and 339 DF,  p-value: 4.703e-05

I want to be able to get the output as a text string and put that into a Text Box in a report window.

@MathStatChem ,
      Before I go too far ahead, are you not wanting to use R Get() ? Did you try using R Get() and then using that information as input to the text box ? 

[#3]

From what I can see, R Get() will get the values from an R data structure or variable (number, string, matrix, list, or data frame), but not the standard output.

@MathStatChem , 

Try this: 

R Init();

dt=open("$SAMPLE_DATA/Cars.jmp");
R Send(dt);

R Submit(
	"
	model = lm(Chest.decel ~ Wt,data = dt)
	t = summary(model)
	
	# Use names function to determine what are the objects that exist 
	names(t)
	
	# Extract and cast into data frames 
	Residuals = as.data.frame(t$residuals)
	Coefficients = as.data.frame(t$coefficients)

	"
);

ResidJMP = R Get(Residuals);
ResidJMP << New Data View;
CoeffJMP = R Get(Coefficients);
CoeffJMP << New Data View;  

RTerm();

Close(dt,"No Save");

Thanks for the suggestion.   I know if I can put the R results into a R data object, then I can use R Get() to retrieve the results.  However, it would be a lot easier to just get the stdout results as a text string, at least for my purposes.

 Log Capture() may do what you want.

Names Default To Here(1);

R Init();

dt = Open("$SAMPLE_DATA/Cars.jmp");
R Send(dt);

R_stdout = Log Capture(R Submit("
	summary(lm(formula=Chest.decel ~ Wt, data=dt))
	"));

R Term();

New Window("example", Text Box(R_stdout));
