UNCkeytron: Create a KEY for the scantron

In ProfessR: Grades Setting and Exam Maker

Create a KEY for the scantron

Description

Create a KEY for the scantron

Usage

UNCkeytron(g, fout, LAB = "KEY")

Arguments

g	vector of correct answers
fout	output file name
LAB	Label to print on key

Details

Given a vector of correct answers the program will create a postscript file with a facsimile of the scantron used for examinations at UNC Chapel Hill. The Bubbles will be filled and can be used to prepare a number 2 pencil version.

Value

Side effects

Note

Currently only eps outputs - future versions may be different. At this time, the code creates postscript code, which can be converted to png, pdf or other formats with software outside of R. In linux I use a perlscript, ⁠ /home/lees/Progs/Perl/ps2png.prl files.eps ⁠ which, in turn, calls, epstopdf and ⁠ gs -dBATCH -sDEVICE=png16m -dNOPAUSE -r200 -sOutputFile=$outpf $inpf ⁠
