hi Barry thanks for your explanation. actually i don't know much about python, also i know nothing about C++, but i am willing to learn.
i had a look at the Rpy documentation, it looks quite good. I can see you can use R functions within Python. However, i don't really want to do that unless it is necessary, because all my codes necessary for calculation are already written in R ! I am not sure but I guess it is possible to get the numerical inputs from the GUI, initiate the already written R codes (dot R files) to calculate and produce the graphs/number, feed it back to Python/PyQt, and finally display in the GUI. Is that possible? graham -- View this message in context: http://r.789695.n4.nabble.com/Link-between-Qt-GUI-and-R-tp3804976p3807563.html Sent from the R devel mailing list archive at Nabble.com. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
