Dear Sir, Please excuse my akwardness as I a new to R and computers, but would kindly appreciate help. { a <- sample (1:10,100,replace=T ) b <-sample(10:20,100,replace=T) c <- sample(20:30,100,replace=T) d <- sample(30:40,100,replace=T) e <- sample(40:50,100,replace=T) } d1 <- a d2 <- b d3 <-c d4 <- d d5 <- e
data.frame(d1,d2,d3,d4,d5) dd <- data.frame(d1,d2,d3,d4,d5) dd sd(d1) summary(d1) sd(d2) summary(d2) sd(d3) summary(d3) sd(d4) summary(d4) sd(d5) summary(d5) I am a beginner to R and am trying to learn statistical probability. I have started Dr. Levine and Dr Kerns books. So far from the usual sources, I haven't found the answers to the following questions and would greatly appreciate any assistance that anyone might kindly share. If I run this code, how do I look for duplicate rows and how can I adjust the SD of the sample function to make the chances of a duplicate row occur more often ? How do I export the dd data frame to excel?
