describing participants executions of an exercise and improving after those executions. LOGIN is the participant identifier, IMPROVE shows if the particpant improved or not, RESULT ranges from 0 to 66 and is the result of each execution and EXECNUMBER is the execution number of the exercise (meaning first execution, second execution, etc) .

I need to build a cross table with RESULT in X exe (from 0 to 66) and EXECNUMBER on Y exe (from 1 to 58) which I did using this code

Code:
> myData <- read.csv(file='data.csv',sep=',',header=T)
> res <- table(myData$EXECNUMBER,myData$RESULT)
But now I was asked to fill the table with the proportion of people with IMPROVE=YES

Being:
Code:
n number of participants for each execution number and for each result. 
m number of participants for each execution number and for each result and IMPROVE=YES
I need to fill the table with m/n
