lln.ani {animation}  R Documentation 
This function plots the sample mean as the sample size grows to check whether the sample mean approaches to the population mean.
lln.ani(FUN = rnorm, mu = 0, np = 30, pch = 20, col.poly = "bisque", col.mu = "gray", ...)
FUN 
a function to generate random numbers from a certain distribution:

mu 
population mean; passed to 
np 
times for sampling from a distribution (not the sample size!); to examine the behaviour of the sample mean, we need more times of sampling to get a series of mean values 
pch 
symbols for points; see Details 
col.poly 
the color of the polygon to annotate the range of sample means 
col.mu 
the color of the horizontal line which denotes the population mean 
... 
other arguments passed to 
np
points are plotted to denote the distribution of the sample mean;
we will observe that the range of the sample mean just becomes smaller and
smaller as the sample size increases and ultimately there will be an obvious
trend that the sample mean converges to the population mean mu
.
The parameter nmax
in ani.options
means the maximum
sample size.
None (invisible NULL
).
The argument pch
will influence the speed of plotting, and for a
very large sample size (say, 300), it is suggested that this argument be
specified as '.
'.
