Hi!

Suppose I have a dataset as follows

pd = c(10,7,10,11,7,11,7,6,8,3,12,7,7,10,10)

I wish to calculate the mean, standard deviation, median, skewness and kurtosis i.e. regular standard statistical measures.

average = mean(pd)
stdev    = sd(pd)
median = median(pd)
skew    = skewness(pd)
kurt     =  kurtosis(pd)

Q. No (1)

How do I get these at a stretch using some R package? I came across moments and e1071 package, but I am not sure which one to use and how?

Q. No. (2)
Many times I came across the command

set.seed(1234)

What is the significance of this command. I understand this is related to random number generation. But what does it do?

Thanking in advance

Amelia
