R Get() function returns error

I am having problem getting a data frame from R to JMP.

This little simple test works fine and returns "1" as it should

clear symbols();
R Init();
R submit("
x <- 1
");
a = R Get(x);
R Term();
a

 

A longer R code looking something like this

clear symbols();

R Init( );
R submit("\[
library(dplyr)

.. 20 lines of code ..
head(X)  // Output of "head(X)" gives the expected first five rows of X, good
]\");

R Get(X) << NewDataView; 

Returns the following error:

"Warning: Error in readBin(fc, "integer", n = SRBX_FILEHEADER_LENGTH) :
Warning: object 'SRBX_FILEHEADER_LENGTH' not found
Unknown"

Any clues?

Thanks for the advice. It made me go through the code again. 

 

The error message somehow disappear if I put  "R Term()" at the start of of the script. I think the error came because previous R connections had not been terminated 

Re: R Get() function returns error

While I am not familiar with that particular error I sometimes see strange things when exporting tibble columns as you are probably doing using dplyr.  You might be able to narrow down the issue by subsetting columns (and/or using slice() to subset rows) and exporting smaller tables.

Names default to here( 1 );

R Init( );

R submit("\[
library(dplyr)
data(mtcars)
df = mtcars %>% add_rownames 
]\");

R submit("dfout = select(df, 1:3)");
R Get(dfout) << NewDataView;

R submit("dfout = select(df, 4:6)");
R Get(dfout) << NewDataView;

R Term();
