Hi team,I'm trying to pass macro variable into R script in Proc iml. I want to do change
variable in color= and export the result with different file name.If I don't use macro,
the code work well. But when I try to use macro below, I got error message: "Submit
block cannot be directly placed in a macro. Instead, place the submit block into a file
first and then use %include to include the file within a macro definition.". After
reading the message, I still not sure how to fix the problem in the code. Anyone can help
me?
Thank you,Kai
%macro pplot(a);proc iml;
submit / R;

mpg %>% filter(hwy <35) %>% ggplot(aes(x = displ, y = hwy, color = &a)) +
geom_point()ggsave("c:/temp/&a..jpg")
endsubmit;
quit;%mend;%pplot(drv);%pplot(cyl);

Two problems I see. 1) you posted to R-help using html whereas the
mailing list is a plain text venue, and 2) I reasonably sure that's a
SAS error message and we don't consult on SAS problems.
If you strip out the stuff involving "&a" and add back in the elided
line-breaks the R code runs without error.
