Dear all, After spending a few week trying to figure out the problem with the ReadMe package when run under windows, I have just found the following fix. The main culprit preventing your Windows OS from properly accessing the makerfile is due to the 'single quotes' that are added to the file path in the undergrad script (e.g. 'C:\python27\python.exe' instead of just C:\python27\python.exe). This also becomes a problem when the script accesses the control.txt and tablefile.txt files. This might be fine (or even required) under other OSes, but under Windows this actually becomes problematic due to the way the OS reads file paths. Therefore I have devised the following (temporary) fix: Note 1 This fix assumes that you have installed Python 2.xx or 3.xx and have properly configured your PATH environmental variable). I have tested this fix with the most recent R versions Note 2 I recommend implementing this under Rstudio because it displays line numbers, but this is also doable under the vanilla Rgui Note 3 I only write about the minimum amount of fixes you need in order to properly run the undergrad function (which is necessary if you were to run the demo(clinton) script), but I have yet to test whether the ReadMe script needs further modification for windows when deciding to run other datasets with different operators. 1 start R 2 load the Readme package --> library(ReadMe) 3 type the following command --> fix(undergrad) 4 find line 10-12, which shows the Python2 (makerfile) lines of code: if (python3 == FALSE) { call <- paste(system.file("'","makerfile", package = "ReadMe"), *"'" * sep = "") } 5 remove the double quotes + singles quotes + the extraenous commas between the system.file() brackets. This leaves just the following code (note that R does not care much about the spaces or tabs that you'll delete): if (python3 == FALSE) { call <- paste(system.file("makerfile", package = "ReadMe"), sep = "") } 6 repeat the same procedure for line 14-16 (this fixes the Python3 makerfile), which results in else { call <- paste(system.file("makerfile3-0.py", package = "ReadMe"), sep = "") } 7 Do this also for the control-file (lines 43-44) and the table-file (lines 45-46), this should result in the following lines of code: call <- paste(call, "--control-file", paste(control, sep = "")) call <- paste(call, "--table-file", paste(table.file, sep = "")) 8 Save your modifications (under Rgui you will be prompted with save when you close the edit window). 9 Run demo(clinton) Final note: This fix for the undergrad function is temporary until you restart R. You could technically save the fixes on a permanent basis or write an script that automatically runs at start-up, but I just save the modified script in a separate text file and copy/paste it whenever I need to run the ReadMe package. Either way, until the makers of the ReadMe fix the undergrad function for windows you'll have to modify the undergrad function by yourself.
