R help - May 2010 - plot formula 'x' is missing?

Hello,

I'd like to plot the logistic function for a specific model like this:
>
plot(formula=y~1/(1+exp(5.0993-0.1084*x)),data=data.frame(x=seq(0,100,length.out=1000)))
Error in is.function(x) : 'x' is missing 

However, I get the 'x' is missing error above and don't know how to
fix it ...

Can anyone advice?
Thanks in advance,
Best regards,
Giovanni

Hi Giovanni,

curve(1/(1+exp(5.0993-0.1084*x)), 0, 100)

HTH,
Jorge
