Dear all, I have 2 questions maybe more for developpers, and about an S-PLUS script. I think that people from R and maybe Bioconductor could also help me. 1-- When producing a graph with S-PLUS (under Windows XP), it is possible to select (with the mouse) an area of the graph in order to highlight the rows corresponding to the selected plots on the dataset sheet. In my case I have to plot about 100 graphs, so I wrote a script with a loop to do that automatically. Each time you pass through this "for" loop the graph is done. My problem is that with this way to build graphs, I lost the possiblity to highlight data in the data set sheet by defining a zone with the mouse on the graph sheet. (actually it is impossible to define a zone on the graph with the mouse) Does anyone already encountered this problem, and would handle a solution ? I saw maybe the brush() function to be applied on the loop, but this seems to return only the row indices and I would like a variable more informative that is on a column in my data set sheet. 2-- In my script I want to use the menuSubset() command. It works in command line, but I would like this command to appear as a graphical window. I can have the window with the following command line: guiDisplayDialog("Function", "menuSubset") but the problem is that the script continues to run, and does not wait for the user to click on the "OK" button in order to wait for the result of the command Subset, which is a matrix needed further on the script. Do you know a way to pass arguments from the data filled in the window to the script, or to force S-PLUs to wait ? Any help gratefully welcome, Florence Combes.
