I am revising a program that I wrote when I was very new at R (2007ish), and while I have been able to write very nice and fast code for almost all of it, there is one issue that I cannot seem to do it in less than 40 ugly and computationally expensive lines.
I have a data frame that contains one variable: theFrame <- data.frame(theValues=runif(150,-10,10)) I would like to write a function that would assign each of these values a factor, and I need it to meet several criteria: (1) There are 15 factors. (2) I need there to be exactly 10 elements assigned to each factor. Now here is the tricky part: (3) I would like to assign the factor probabilistically. The lower theValue is for a row, the lower factor I would like it to receive. So values close to -10 should have a really high probability of being assigned factor 1. If assigning factors is to tricky I would settle for placing theValues in a 10 x 15 matrix where the lower values would be more likely to end up in column 1 (again, values close to -10 should have a really high probability of being assigned to column 1.). Any ideas? I have thought at times I was painfully close only to realize I was completely wrong.
