描述参与者执行练习并在执行后改进。 LOGIN是参与者标识符，IMPROVE显示参与者是否改进，RESULT范围从0到66并且是每次执行的结果，EXECNUMBER是练习的执行编号（意味着第一次执行，第二次执行等）。
我需要在X exe（0到66）中建立一个带有RESULT的交叉表，在Y exe（从1到58）上用EXECNUMBER构建一个交叉表，我用这个代码做了
> myData <- read.csv(file='data.csv',sep=',',header=T)
> res <- table(myData$EXECNUMBER,myData$RESULT)
但现在我被要求用IMPROVE = YES
的人填充表格存在： n每个执行号码和每个结果的参与者数量。 m每个执行号码和每个结果的参与者数量，IMPROVE = YES
我需要用m / n填充表格
答案 0 :(得分：0)
查看subset函数（?subset）。
myDataSubsetYes <- subset(myData, myData$IMPROVE == "SI")
table(myDataSubsetYes$EXECNUMBER, myDataSubsetYes$RESULT)
（顺便说一句：IMPROVE栏中没有“是”）
