My R function is calling a c++ code which will “cout” some lines during its iterations, I can see this lines in windows R called by Command Prompt. But I could not see anything when I directly open R in windows os.
I wonder is there any way to see the c++ output from R under windows but not in command prompt?
Or if not, can R display something while it’s calling c++ at background?
Thank you for your help.
See the Printing section of Writing R Extensions. You want
Rprintf.
