Felix,
there may be more elegant ways of plotting the normal curve, but given your
current program, you can simply change your plot statment to use a formula:
plot(f.x ~ x, type="l", xlim=c(-5,5))

Hello,
i have written this little function to draw different normal distributions:
n.Plot <- function(x,my,sigma) {
e <- exp(1)
names(x) <- x
f.x <- (1/(sigma*sqrt(2*pi)))*e^(-1*(((x-my)^2)/2*(sigma^2)))
plot(f.x,type="l",xlim=c(-5,5))
return(f.x)
}
if i define x like this:
x <- seq(-5,5,0.01)
Now
n.Plot(x,0,1)
DOES draw the correct plot, but the x-axis is labeled from 0 - 1000.
If i give the plot function the xlim=c(-5,5) option, the plot is only drawn
for the first 5 values of x.
How do i tell plot not to take the indices of x, but the values (or their
range) of x for labeling the x-axis ?
