Which variable exist after random
Dear R-helper, How could I count only some variable was exist after running sample (random) function.
Or is this what you want? Tab <- table(sample(testx, replace=TRUE)) Tab[ Tab > 0 ]
For example,
testx <- factor(c("Game","Paper","Internet","Time","Money"))
for(i in 1:2) {
+ x <- sample(testx,replace=TRUE) + print(x) + } [1] Money Money Time Internet Time Levels: Game Internet Money Paper Time [1] Time Money Game Money Money Levels: Game Internet Money Paper Time
The result above Game, Internet, Money, and Time only exist and "Paper" was missing. Best, Sofyan
