What about something like this:

#Create dummy data
mydf=data.frame(matrix(rnorm(1000), ncol=100))

#Obtain summary stats

my.vars=apply(mydf, MARGIN=2, FUN=var)
my.std=sqrt(my.vars)

#Plot summary stats
plot(my.vars, col="red")
points(my.std, col="blue")

Subject: Re: [R] Deviation standard & variance
 
I have a data set consisting of 364 variables and I need to graph the
standard deviation and variance of each variable as only the function sd ()
or var () is not enough. And I want to know how I can graph this?
