R help - Mar 2023 - Problems with foreign

Good day
My name is Jos? Oscar, I'm from Mexico and I have some questions about
foreign in your write.foreig( ) function. We know that this function
generates the inputs to be able to run them or execute them in another
program like SPSS, SAS or Stata. In these cases, when creating an example
file, a matrix and using the function to execute the .sps file directly
from SPSS, I don't care or work based on the SPSS environment. With Stata
the problem does not arise, but this same problem also arises with SAS, in
that sense or question, how could I solve this? Do you have any guides or
tutorials on the correct use of the function?

This is the code:
x<- matrix(data = sample(1:100,
                         100),
           nrow = 10, ncol = 10)

x2<- as.data.frame(x)

write.foreign(x2, "x2_spss.txt", "x2_spss.sps", package =
"SPSS")

I don't really understand the question. Not sure what the problem you 
are seeing when you attempt to get SAS-style output. I went to the help 
page for `write.foreign`:

?write.foreign

...? and the Arguments section clearly shows that although "SPSS" is
the
default value, that any of the other recognized values for the format of 
the output would be accepted.

Perhaps you are so inexperienced with R that you don't even know how to 
access the help system?

When I changed the "package" argument to "SAS", ...? I get
SAS code:

* Written by R;
*  write.foreign(esoph, datafile, codefile, package = "SAS") ;

PROC FORMAT;
value agegp
      1 = "25-34"
      2 = "35-44"
      3 = "45-54"
      4 = "55-64"
      5 = "65-74"
      6 = "75+"
;

value alcgp
      1 = "0-39g/day"
      2 = "40-79"
      3 = "80-119"
      4 = "120+"
;

value tobgp
      1 = "0-9g/day"
      2 = "10-19"
      3 = "20-29"
      4 = "30+"
;

DATA  rdata ;
INFILE  "/tmp/RtmpFcHZ9L/file6a7222461f1c"
      DSD
      LRECL= 15 ;
INPUT
  agegp
  alcgp
  tobgp
  ncases
  ncontrols
;
FORMAT agegp agegp. ;
FORMAT alcgp alcgp. ;
FORMAT tobgp tobgp. ;
RUN;
